摘要

通道均衡是实现地面运动目标测速、定位的前提条件.本文研究机载多通道雷达基于空时二维回波数据的通道均衡问题.利用杂波在沿航迹多幅多普勒锐化图像(DBS

Doppler Beam Sharpening)间的相位关系

提出一种基于数据相位矢量的通道盲均衡算法.理论分析和实测数据处理表明该算法能有效均衡通道误差

并对运动目标信号污染具有稳健性.

Abstract

Channel balance is the prime problem for target parameters estimation and location.We focus on channel mismatch and target signal contamination which preclude the performance described in much of the theoretical space-time adaptive processing (STAP) literature.Exploring phase relation among along-track Doppler beam sharpening (DBS) images

a channel calibration algorithm based on second order moments of phase vector is presented.The effectiveness for channel mismatch and the robustness for target signal contamination are confirmed by performance analysis and experimental data.
