雷达信号处理,针对现代雷达信号处理的主要方式，运用数字信号处理理论和 Matlab 软件研究雷达信号处理的仿真 问题。提出了一个仿真模型，该模型可以仿真雷达信号、热噪声与杂波的产生和雷达系统中信号的动态处理 过程。用 Matlab 对某脉冲压缩雷达信号处理系统进行了仿真，得到了雷达系统中各个处理点上的具体信号形 式，既包含幅度信息，又包含相位信息，该模型能较好地满足对雷达信号处理的仿真要求，显示了用 Matlab 仿真雷达信号处理系统的方便、快捷的优点。 (Radar signal processing, radar signal processing for the modern major mode of use of digital signal processing theory and Matlab software simulation of the radar signal processing problems. Proposed a simulation model, the model can be simulation of radar signals, thermal noise and clutter of the radar system in the generation and dynamic signal processing. Using Matlab for a pulse compression radar signal processing system simulation, radar systems have been various points on the treatment of specific signal form contains both amplitude information, but also contains the phase information, the model can better meet the needs of radar signal processing simulation requirements, shows the Matlab simulation using radar signal processing system convenient, fast advantages.)
