Extension and Updating of the Computer Simulation of Range Relative Doppler Processing and Invariant Mapping for MM Wave Seekers. Volume 3. Simulation of a Doppler Beam Sharpening Radar for MM Wave Seekers.

摘要

This report extends the application of Range Relative Doppler Processing RRDP and of the Invariant Mapping Technique to beam doppler sharpening radars, where the goal is to map a large area on the ground. In this application the antenna follows a horizontal path while scanning a wide azimuth interval. Two programs are developed: DOPFP.FOR and DOPXY.FOR. The first detects targets with the sequence of footprints. The second program uses invariant mapping to generate a file which contains reflectivity data versus absolute coordinates for a selectable x-y window. An example illustrates the detection of (4) forty randomly distributed scatters. The performance is quite good, except that the azimuth resolution is poor for footprints at very low azimuth angles. All the results are in complete agreement with the theory. (Author).
