The application of quasi-optical techniques to millimetre wave radar

Leeson, Michael. J. January 1993 (has links)
The application of Quasi Optical techniques has been of great benefit to the field of instrumentation for frequencies between 750Hz and several hundred OHz. The application of Quasi Optical techniques to millimetre wave radar, described in this thesis, has produced an FMCW Doppler radar capable of operation at 940Hz and 1400Hz. Total polarization agility and a capability to operate over a very wide bandwidth is demonstrated. Quasi Optical circuits are proposed as solutions for many of the system requirements, and these are fully analyzed. Significant benefits of these techniques are demonstrated, and future improvements are suggested. A new design tool, in the form of a program, for Quasi Optical circuit analysis is presented and is used for the analysis of all the optical circuits in this thesis. The program has speeded up the design process for optical circuits. A new type of feedhorn is described and characterized. Its performance compares well with existing feedhorns, and it provides a low cost alternative to existing antenna requirements.

Bathymetric mapping with QuickBird data

Densham, Martin P. J. 09 1900 (has links)
Two algorithms are used to determine bathymetry in the littoral region using QuickBird multispectral satellite observations. The algorithms determine water-leaving radiance and convert this to water depth values. The first algorithm uses a ratio of two wavebands and the second uses the sum of several wavebands. Relative bathymetric errors are determined for the clear water of Looe Key (USA) and the turbid water of Plymouth Sound (UK). Bathymetric measurements from LIDAR and chart data are compared to derived depths to assess their accuracies. An amended version of the ratio method is proposed for use in turbid water to improve accuracy. The results show that the standard ratio and turbidity algorithms have a relative error of 11.7% and 16.5% respectively in clear water. In turbid water the average error of the turbidity algorithm is 11.6% and the amended ratio algorithm average error is 13%. / Royal Navy
