| 摘 要： | 为了提高引信的最佳毁伤控制能力,本文结合LFMCW引信特点对差拍信号进行了理论分析,得出了影响距离分辨率、速度分辨率等指标的因素,并利用Simulink软件搭建了相关的仿真模型,对通过二维傅里叶变换获取距离、速度信息的方法进行仿真验证。该模型可以模拟引信回波信号、噪声信号的产生以及中频信号处理的过程。仿真结果验证了算法的可行性与模型的准确性,为引信系统优化设计奠定了基础。

| Abstract: | In order to improve the optimal damage control ability of LFMCW fuze,the beat signal is analyzed theoretically combining with the characteristics of fuze in this paper.The factors affecting range and velocity resolution are obtained.The simulation model is established in Simulink,and the method of obtained distance and velocity by two-dimensional Fourier transform is simulated.The model can simulate the echo signal and noise of the fuze,and IF signal processing process.The simulation results verify the feasibility of the algorithm and the accuracy of the model,which lays a foundation for the optimal design of fuze. |
