With its unique array arrangement, the detection system radar has both space diversity gain and waveform diversity gain, and is currently recognized as a stealth target buster. The detection system radar is applied to a high-speed moving platform. Using distributed cooperative detection technology,non-coherent fusion detection based on signals can further improve the detection of stealthy targets. Aiming at the high-speed motion radar signal processing algorithm, this paper mainly studies the following three aspects: the first content is the analysis of the waveform characteristics: the basic principles and characteristics of the radar are explained; then the three orthogonal waveforms commonly used in the radar are introduced, including Stepwise frequency division chirp signal, quadrature phase coded signal and mixed-signal; the second content detects radar targets and analyzes the correlation between the scattering coefficients of different radar channels; for scenarios where the scattering coefficients between the channels are non-coherent Introduced two kinds of non-coherent fusion detectors based on generalized likelihood ratio algorithm: centralized detector and double threshold detector; the third content radar multi-target pairing is aimed at the problem of radar multi-target pairing with large inertial navigation error. A multi-target pairing algorithm that uses target delay information and combines the radar’s multi-channel information redundancy characteristics is presented. An expression for judging the correctness of target pairing is derived, and the target pairing steps are given. The relationship between the amount of algorithm operation and the number of radar stations and the number of targets is analyzed in conclusion.

雷达信号处理算法及检测系统仿真

凭借其独特的阵列布置，探测系统雷达既具有空间分集增益又具有波形分集增益，并且目前被认为是隐形目标克星。该探测系统雷达应用于高速移动平台。使用分布式协作检测技术，基于信号的非相干融合检测可以进一步提高对隐身目标的检测。针对高速运动雷达信号处理算法，本文主要研究以下三个方面：第一个内容是波形特征的分析：解释了雷达的基本原理和特性；然后介绍了雷达中常用的三个正交波形，包括逐步分频线性调频线性调频信号，正交相位编码信号和混合信号。第二个内容是检测雷达目标并分析不同雷达通道的散射系数之间的相关性。针对信道间散射系数非相干的场景，基于广义似然比算法，介绍了两种非相干融合检测器：集中检测器和双阈值检测器；第三内容雷达多目标配对是针对惯性导航误差较大的雷达多目标配对问题。提出了一种使用目标延迟信息并结合雷达多通道信息冗余特性的多目标配对算法。导出判断目标配对正确性的表达式，并给出目标配对步骤。
