摘要
为了提高雷达测距测速的精度,提出一种信号处理的改进算法,并利用Simulink软件搭建了相关的仿真模型。该模型可以模拟雷达信号、噪音信号的产生以及中频信号处理的过程。与传统信号处理算法不同的是,本算法在适当增加FFT运算点数的同时还加入了Chirp-Z变换。仿真结果验证了模型的可行性与算法的可靠性,结果表明该算法可显著提高雷达的测距精度。
In order to improve the accuracy of radar range gun, an improved algorithm for signal process-ing was put forward and the related simulation models were built by Simulink software. The model cansimulate the radar signal, the generation of the noise and the treatment process of IF signal. Unlike thetraditional algorithm, this one increases the number of points of the FFT appropriately and joins theChirp-Z transformation. The simulation results verify the feasibility of the model and reliability of thealgorithm. The results show the algorithm can significantly improves the ranging precision of the radar.
