Multi-channel multistatic synthetic aperture radar with stationary receiver and data processing method thereof

摘要

Disclosed is a multi-channel multistatic Synthetic Aperture Radar (SAR) stationary receiver and a data processing method thereof, in which one channel of radio frequency signal and N channels of echo signals are received; the one channel of radio frequency signal is decomposed into N+1 channels of direct signals, one of the N+1 channels of direct signals is demodulated to an intermediate frequency signal; the intermediate frequency signal is detected in a time domain, a rising edge trigger signal is generated when detecting a pulse signal in the intermediate frequency signal, the rising edge trigger signal is amplified; and the N channels of direct signals and the N channels of echo signals are collected upon reception of the rising edge trigger signal.
