一种提高雷达接收相干性的新算法

A New Algorithm for Improving Radar Receiving Coherence

提出了一种新的幅相联合处理算法，并对其接收相干性能进行了数学分析和计算仿真．理论分析和实际测试表明：该算法改善因子性能完全不受发射脉冲的随机初相、振幅、脉间频率抖动的限制，实现了对检测动目标信号的准匹配滤波过程．相对于其它算法，该算法进一步提高了雷达信号处理系统的接收相干性。

This paper proposes a new amplitude-phase joint processing algorithm. And the mathematical analysis and simulation is carried out for its characteristics of receiving coherence. It shows that the perform- ance of the improvement factor in the algorithm is entirely independent on the random initial phase, amplitude and frequency fluctuation between pulses, which realizes the near match filtering process of moving target sig- nal detection. Compared with other algorithms, the new one go further for improving the receiving coherence of the radar signal processing system.
