Design And Implementation Of Signal Reconnaissance And Sampling Processor Of Ultra-wideband Radar

Ultra-wideband radar is a new radar system, with a low interception,anti-jamming, and anti-destroying properties. With the rapid development ofultra-wideband radar, ultra-wideband signal occupies a large bandwidth, whichpresents a huge challenge to the traditional reconnaissance system. In this paper, theultra-wideband radar signal acquisition processor with the characteristics of real-timeprocessing multi-signal functions, large instantaneous bandwidth, good sensitivity anddynamic range, high parameter measurement accuracy are studied.Finally theultra-wideband radar signal acquisition processor is designed and realized.First of all, this paper introduces the basic concepts and the common signalforms of ultra-wideband signal, including impulse signals and pulse compressionsignal, and analyzing the characteristics of ultra-wideband radar signal. Secondly, thispaper introduces the basic technical principles of ultra-wideband radar signalacquisition processors, including digital channel technology of the complex signals,sliding adaptive threshold of signal detection method, the split pulse parametersapproach, signal search method, AGC and other key technical principles. Then,according to a spaceborne radar ultra-wideband signal acquisition and processingneeds, given the realization scheme of ultra-wideband radar signal acquisitionprocessor. Finally, according to the design requirements of the system, this paperdesigns and realizes the ultra-wideband radar signal acquisition processor, tests andanalyses the systems key indicators.
