【摘要】：脉冲行进间探测雷达是一种边行进边探测的脉冲体制雷达,常规的脉冲雷达是根据目标的多普勒信息实现目标检测的,但在雷达行进状态下,雷达信号处理解算的多普勒信息已不能真实反映目标的运行信息,而且很可能将静止目标当成运动目标。因此,为了实现有效探测,需在信号处理软件的设计中引入相应的补偿手段,修正目标的多普勒信息。本课题以脉冲行进间探测雷达为研究背景,主要对雷达信号处理软件进行设计和实现,主要的工作包含:1、介绍脉冲雷达脉冲压缩、动目标检测、恒虚警检测等信号处理算法的理论和方法,并提出在行进状态下,雷达探测存在的问题以及为解决这些问题进行速度补偿等补偿算法的理论和方法;2、结合工程要求,对信号处理软件进行需求分析,将信号处理软件分解成数据接收分配、脉冲压缩、动目标检测、速度补偿、恒虚警检测和检测信息输出6个功能模块,并分析了信号处理软件需要达到的实时性、接口带宽等性能要求,同时也提出了信号处理软件的可靠性、安全性需求;3、根据需求分析,完成了信号处理软件6个功能模块的软件设计和实现,并分解性能等软件设计要求,提出了各功能模块的设计约束,设计详细的软件执行流程;4、为保证软件功能、性能和运行的稳定性、可靠性,对软件进行测试是必要的。通过搭建的测试平台,测试除了验证软件的功能和性能外,还需要对软件设计中存在的风险,通过设计合理的测试用例充分验证。
[Abstract]:Pulse travel detection radar is a kind of pulse system radar which detects while traveling. The conventional pulse radar detects the target according to the Doppler information of the target, but in the state of radar travel, The Doppler information calculated by radar signal processing can no longer reflect the moving information of the target, and it is very likely that the stationary target can be regarded as the moving target. Therefore, in order to realize effective detection, the corresponding compensation means should be introduced in the design of signal processing software to correct the Doppler information of the target. Based on the research background of pulse travel detection radar, this paper mainly designs and implements the radar signal processing software. The main work includes: 1. The pulse compression and moving target detection of pulse radar are introduced. The theory and method of signal processing algorithms such as CFAR detection, and the problems existing in radar detection under traveling state, and the theory and method of compensation algorithms for speed compensation in order to solve these problems are put forward. The signal processing software is decomposed into six function modules: data receiving and distributing, pulse compression, moving target detection, speed compensation, constant false alarm detection and detection information output. At the same time, the reliability and security requirements of the signal processing software are put forward. The software design and implementation of the six function modules of the signal processing software are completed, and the software design requirements such as decomposing performance are presented. The design constraints of each functional module are put forward, and the detailed software execution flow is designed. 4, in order to ensure the software function, Performance and running stability, reliability, software testing is necessary. In addition to verifying the function and performance of the software, it is necessary to test the risks in the software design and fully verify the design of reasonable test cases through the built test platform.
