摘要/Abstract

摘要：

高脉冲重复频率(high pulse repetition frequency, HPRF)和差天线雷达在导引头中具有重要应用, 其在超低空运动目标检测时, 面临多重距离模糊的地海面杂波抑制问题。针对上述问题, 提出一种和差通道时域对消的杂波抑制方法。该方法基于和差通道间杂波功率谱相关度较高的特征, 联合利用差-差-双差通道数据估计杂波协方差矩阵, 拟合和通道的杂波协方差矩阵，并基于最小方差准则实现和通道杂波对消, 提升了雷达导引头的杂波抑制性能。仿真实验验证了该方法的有效性。

Abstract:

High pulse repetition frequency (HPRF) sum difference antenna radar has important applications in missile-borne. It faces the problem of ground and sea clutter suppression with multiple range ambiguity in ultra-low altitude moving target detection. In view of the above problem, a clutter suppression approach of sum-difference channel time-domain cancellation is proposed. Based on the high correlation of clutter power spectrum between sum and difference channels, this approach uses difference-difference-double difference channels data to estimate clutter covariance matrix, and fits the clutter covariance matrix of sum channel, and achieves clutter cancellation of sum channel based on minimum variance criterion, which improves the clutter suppression performance of missile-borne radar. Simulation results verify the effectiveness of the proposed approach.

Key words: high pulse repetition frequency (HPRF), sum-difference antenna, missile-borne radar, time-domain cancellation, clutter suppression
