International Telemetering Conference Proceedings / October 28-31, 1996 / Town and Country Hotel and Convention Center, San Diego, California / The use of high bit rates in the missile testing environment requires that the receiving
telemetry system(s) have the correct signal margin for no PCM bit errors. This requirement
plus the fact that the use of “redundant systems” are no longer considered optimum
support scenarios has made it necessary to select the minimum number of tracking sites
that will gather the data with the required signal margin. A very basic link analysis can be
made by using the maximum and minimum gain values from the transmitting antenna
pattern. Another way of evaluating the transmitting antenna gain is to base the gain on the
highest percentile appearance of the highest gain value.
This paper discusses the mathematical analysis the WSMR Telemetry Branch uses to
determine the signal margin resulting from a radiating source along a nominal trajectory.
The mathematical analysis calculates the missile aspect angles (Theta, Phi, and Alpha) to
the telemetry tracking system that yields the transmitting antenna gain. The gain is
obtained from the Antenna Radiation Distribution Table (ARDT) that is stored in a
computer file. An entire trajectory can be evaluated for signal margin before an actual
flight. The expected signal strength level can be compared to the actual signal strength
level from the flight. This information can be used to evaluate any plume effects.
