用相位梯度法校正超宽带雷达系统的相位误差

摘要

The phase error of UWBR(Ultra_WideBand Radar) system based on LFM signal, will affect the result of the pulse compression of the radar system. The phase gradient algorithm presented in this paper can estimate the phase error of the system effectively, and improve the performance of the pulse compression.%线性调频（LFM）信号体制的超宽带雷达（UWBR）系统的相位误差，会影响雷达系统脉冲压缩的结果。本文提出的相位梯度（PG）算法，能够有效地估计系统相位误差，改善脉冲压缩的性能。
