Synthesis of a Basic Range Channel for Implementation of a Complete Mti by Range-Gated Filtering

摘要

A range-gated channel was constructed for use with various Doppler filters in building the basic element of a radar Moving-Target-Indicator (MTI) by Range-Gated-Filtering (RGF). Improvement over existing systems was accomplished by circuit simplification and solid-state design incorporating MOS devices in sampling circuits and d-c coupled amplifiers. Performance of the channel, using an R-C high-pass filter as the simplest Doppler filter, was compared to that of the delay-line canceler MTI of the AN/UPS-1 air-search radar. (Author)
