Radar system for discriminating between first and multi-time around echos.

摘要

A radar system for determining first time around targets from multiple time around targets using two radar pulse trains of different pulse repetition intervals (31) and thresholding means (35). Echos from pulses at each pulse repetition interval being compared (37) to determine first time around targets from subsequent time around targets. The radar system using thresholding levels to determine an echo and being less prone to problems of coincidence gate clashing with high duty cycles.
