宽带直接采样接收机的高速运动补偿方法
A high velocity compensate method for wideband direct sampling receiver
摘要
Abstract
The mathematical model of high velocity motion targets of an echo was established for a wideband direct sampling digital receiver. The effect of high velocity on range profile and inverse synthetic aperture radar (ISAR) imaging was analyzed. An adaptive matched filter method based on wideband direct sampling receiver was presen-ted. A new matched filter was constructed by utilizing assistant low-resolution range and velocity measurement re-sults. The amplitude and phase distortion from high velocity was compensated effectivley and the aberration impact of range profile was avoided. Therefore, the quality of high resolution ISAR imaging is improved. Simulation and experimental results show the effectiveness of the new method.关键词
