说明：  目标和雷达的仿真程序，可以设置目标位置向量、速度、目标散射截面积、距离门限等等，计入高斯噪声，经过混频和傅里叶变化后再显示其距离和多普勒二维图形。
(Target and radar simulation program can be set to the target position vector, velocity, target scattering cross-sectional area, the distance threshold, etc., included in the Gaussian noise, and then after mixing and Fourier transform show its range and Doppler two-dimensionalgraphics.)
