[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.
