Flight Test Results from C-Band Missile Telemetry Project

Kujiraoka, Scott, Felder, Russ, Johnson, Ben 10 1900 (has links)
ITC/USA 2014 Conference Proceedings / The Fiftieth Annual International Telemetering Conference and Technical Exhibition / October 20-23, 2014 / Town and Country Resort & Convention Center, San Diego, CA / Over the past few years, papers have been presented relating to the design and development of a telemetry section used to compare the performance between S-Band and C-Band telemetry links. In addition, the flight test plans to make this comparison have been discussed. Captive Carry Test Flights (on a F-18 fighter jet) over the NAVAIR Sea and Land Ranges at Point Mugu and China Lake were conducted during the April-July 2014 timeframe. In addition a Live Fire Test Flight over the Land Range of the specially outfitted missile was performed in July 2014 as well. This paper will discuss these series of flights tests and provide a performance assessment of the data quality between the C-Band and S-Band telemetry data links. In addition, lessons learned from the various test flights will be included as well. Due to publication deadlines, the results will be summarized at the actual conference.

C-Band Missile Telemetry Test Project

Kujiraoka, Scott, Fielder, Russell 10 1900 (has links)
ITC/USA 2013 Conference Proceedings / The Forty-Ninth Annual International Telemetering Conference and Technical Exhibition / October 21-24, 2013 / Bally's Hotel & Convention Center, Las Vegas, NV / The physics associated with transmitting and receiving a telemetry signal at a frequency greater than an octave above the current operating band is such that an end-to-end evaluation of the complete data link system (both the transmit and receive side) is required. In 2012, Airborne Instrumentation Systems Division (AISD), Naval Air Warfare Center Weapons Division (NAWCWD) was sponsored by the Office of the Secretary of Defense (OSD) to develop a couple of short-range air-to-air missile platforms that use a specially-designed warhead-replaceable telemetry section incorporating three data links: (1) an S-band link to transmit Time- Space-Position Information (TSPI), (2) an C-band link, and (3) an additional S-band link where the latter two are transmitting the same pseudo-random bit sequence at the same effective radiated power level. Flight testing will consist of a series of captive tests conducted over land and water. The tests will be performed under a variety of conditions to induce potential issues caused by multipath, atmospheric ducting, fast-slewing of the tracking antenna, and large propagation losses. Flight testing will culminate with the live-fire of a missile over a military land range. This paper describes the continuing efforts of this test program from these series of flight tests, thus quantifying the performance of C-band telemetry data transmission as compared to the S-band.

Fuzzy Logic Guidance System Design For Guided Missiles

Vural, Ozgur Ahmet 01 January 2003 (has links) (PDF)
This thesis involves modeling, guidance, control, and flight simulations of a canard controlled guided missile. The autopilot is designed by a pole placement technique. Designed autopilot is used with the guidance systems considered in the thesis. Five different guidance methods are applied in the thesis, one of which is the famous proportional navigation guidance. The other four guidance methods are different fuzzy logic guidance systems designed considering different types of guidance inputs. Simulations are done against five different target types and the performances of the five guidance methods are compared and discussed.

TRANSPORTABLE RANGE AUGMENTATION AND CONTROL SYSTEMS FOR MULTIPLE SHOT ENGAGEMENTS

Glenn, Tom, Chavez, Tomas, Toole, Michael T., Markwardt, Jack 11 1900 (has links)
International Telemetering Conference Proceedings / October 30-November 02, 1995 / Riviera Hotel, Las Vegas, Nevada / The Ballistic Missile Defense Organization (BMDO) is developing new Theater Missile Defense (TMD) weapon systems to defend against the rapidly expanding ballistic missile threat. The tactical ballistic missile threats include systems with range capabilities greater than 1000 kilometers. The development and testing of systems such as the Patriot Advanced Capability 3 (PAC-3), the Theater High Altitude Area Defense (THAAD), Navy Area Defense, and the System Integration Tests (SIT) to address the interoperability of this family of systems, will require the development of the Transportable Range Augmentation and Control System for Multiple Shot Engagements (TRACS - MSE). Congress has mandated that these systems be tested in multiple simultaneous engagements. These systems will be tested at several ranges to meet all the developmental and operational testers' needs. Potential range locations include White Sands Missile Range (WSMR), Kwajalein Missile Range (KMR), the Pacific Missile Range Facility (PMRF) and the Gulf Range at Eglin Air Force Base. Due to the long distances separating the target launch site and the interceptor site, the TRACS - MSE will be required at multiple sites for each range used. To be cost effective, transportable systems should be developed to augment existing capabilities. Advances in Global Positioning System (GPS) technology and high data rate receivers make telemetry based solutions attractive. This article will address the requirements for range safety, for Time, Space, Position Information (TSPI) collection and processing requirements to support a TRACS - MSE capability.

EFFECTS OF MULTIPATH-INDUCED DELAY DISTORTION ON PCM/FM FOR ENCANISTERED MISSILES

Vines, Roger M. 10 1900 (has links)
International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Coupling a distortion-free telemetry signal from an encanistered missile by using a pickup antenna inside the canister can be difficult, because the RF energy leaving the missile antenna travels through the canister and is reflected and absorbed in a complex manner before being received by the pickup antenna. In this paper the distortion incurred by a PCM/FM signal is described and used to predict the resulting distortion on the video after demodulation. Effects on bit error rate are presented as a function of delay distortion and bit rate. A demonstrated method of receiving a relatively undistorted telemetry signal using a pickup antenna is described.

TELEMETRY CHALLENGES FOR BALLISTIC MISSILE TESTING IN THE CENTRAL PACIFIC

Markwardt, Jack, LaPoint, Steve 10 1900 (has links)
International Telemetering Conference Proceedings / October 28-31, 1996 / Town and Country Hotel and Convention Center, San Diego, California / The Ballistic Missile Defense Organization (BMDO) is developing new Theater Missile Defense (TMD) and National Missile Defense (NMD) weapon systems to defend against the expanding ballistic missile threat. In the arms control arena, theater ballistic missile threats have been defined to include systems with reentry velocities up to five kilometers per second and strategic ballistic missile threats have reentry velocities that exceed five kilometers per second. The development and testing of TMD systems such as the Army Theater High Altitude Area Defense (THAAD) and the Navy Area Theater Ballistic Missile Defense (TBMD) Lower Tier, and NMD systems such as the Army Exoatmospheric Kill Vehicle and the Army Ground-Based Radar, pose exceptional challenges that stem from extreme acquisition range and high telemetry data transfer rates. Potential Central Pacific range locations include U.S. Army Kwajalien Atoll/Kwajalein Missile Range (USAKA/KMR) and the Pacific Missile Range Facility (PMRF) with target launches from Vandenberg Air Force Base, Wake Island, Aur Atoll, Johnston Island, and, possibly, an airborne platform. Safety considerations for remote target launches dictate utilization of high-data-rate, on-board instrumentation; technical performance measurement dictates transmission of focal plane array data; and operational requirements dictate intercepts at exoatmospheric altitudes and long slant ranges. The high gain, high data rate, telemetry acquisition requirements, coupled with loss of the upper S-band spectrum, may require innovative approaches to minimize electronic noise, maximize telemetry system gain, and fully utilize the limited S-band telemetry spectrum. The paper will address the emerging requirements and will explore the telemetry design trade space.

MISSILE ANTENNA PATTERNS FOR WIDELY-SPACED MULTI-ELEMENT ARRAYS

Vines, Roger 10 1900 (has links)
ITC/USA 2005 Conference Proceedings / The Forty-First Annual International Telemetering Conference and Technical Exhibition / October 24-27, 2005 / Riviera Hotel & Convention Center, Las Vegas, Nevada / Multiple discrete antennas distributed around the circumference of a large missile and driven by one transmitter are sometimes used to radiate telemetry omnidirectionally. But driving discrete antennas separated by several wavelengths around the missile body with a single transmitter can result in an antenna pattern with deep nulls in the roll plane. Varying the relative signal phase or amplitude among the signals driving the antennas as well as the polarization of the antennas can be used to change the nulls in an attempt to decrease the null depth. In this paper the effects of phase, amplitude, and polarization on the roll-plane pattern are examined and measurement data presented.
