摘要

针对加性色噪声和乘性色噪声联合干扰下的雷达运动目标检测问题进行了研究.首先利用循环平稳信号处理原理

分析了加性噪声和乘性噪声联合干扰下的复调频信号的循环统计特性

在此基础上构造了基于二阶循环矩的检测统计量

推导了检测统计量的输出信噪比与观测噪声统计特性的关系.最后利用Monte-Carlo仿真试验得到检测性能的曲线

并与基于时频分布的Wigner-Hough检测器做了比较

仿真试验进一步验证了本文提出的二阶循环矩检测器性能要优于Wigner-Hough检测器.

Abstract

Aiming at the detection problem caused by the maneuvering target under addtive and multiplicative color noise

the detector based on cyclic statistics is constructed

then the relation of detector versus SNR is concluded.The detector properties under various SNR are presented through analyzing the property of the complex LFM signal disturbed by both addtive and multiplicative color noise In the end

the character of the detector and preference is given through Monte-Carlo test in compare with the Wigner-Hough detector.
