摘要
Abstract
A polarimetric active radar calibrator (PARC)is used to calibrate wideband high-resolution radars,confir-ming the high-resolution imaging can accurately characterize radar targets.However,the PARC is an active component and induces additional distortion,affecting the system distortion compensation.This paper was based on the “method of paired echoes”and the distortion compensation in the frequency domain.After transforming the frequency compensation into the filtering in the time domain,we proposed to intercept the time filter for modifying the PARC distortion.The experimental re-sults based on real radar data confirm the accuracy of the theoretical analysis and the proposed modification method and after the modification the PARC can approximately compensate the system distortion.关键词
