小型车载雷达的原理仿真。使用线性调频连续波（LFMCW）波形，探测公路环境下的周围车辆目标，使用距离多普勒方法显示目标的距离和速度信息，并对LFMCW的探测原理做了演示。-Principle small car radar simulation. Using a linear frequency modulated continuous wave (LFMCW) waveform, vehicle detection highway around the target environment, using the Doppler method to display the distance and speed information　the target, and the detection principle LFMCW made a presentation.
