摘要
论文针对相位编码信号距离旁瓣较高的问题,采用了失配滤波的方法来降低距离旁瓣,通过迭代加权最小二乘法求解了失配滤波器的系数;针对相位编码信号多普勒敏感的问题,采用了多普勒通道补偿的方法来进行处理。通过仿真对处理方法进行了验证。
In view of the problem of the high range sidelobe of phase coded signal, the method of mismatched filter is adoptedto reduce the distance sidelobe, the iterative least square method is used to solve the coefficient of the mismatch filter.Doppler channel compensation method is adopted to solve the problem of doppler sensitivity. The correctness of the methodis verified by simulation.
