In order to simulate the return , a radar coherent video echo model is used to simulate target echo , clutter and noise separately . then the three parts which are in the same range cell are added together to form a matrix to represent return in one radar coherent processing interval ( cpi ) . this matrix is called a frame of range doppler data
为了较为全面地对雷达回波进行仿真,采用相干视频回波模型分别模拟雷达目标回波、杂波和噪声,通过在距离单元内叠加的方法,将一个雷达相干处理周期内的回波数据用一帧距离多普勒平面数据表示。
