The invention relates to a complete polarization compensation method and device for an antenna and a waveform, equipment and a medium. The method comprises the following steps: firstly, measuring and calculating cross polarization isolation and orthogonal waveform isolation of a simultaneous full-polarization measurement system radar system, then detecting a target by using the radar system, obtaining an estimated value of a target polarization scattering matrix according to an echo result, and finally constructing a coefficient matrix according to an isolation index. And compensating the estimated value of the polarization scattering matrix by using the coefficient matrix to obtain the true value of the polarization scattering matrix of the target. The target PSM measurement precision is improved by modeling and compensating polarization errors of a radar system. 本申请涉及一种针对天线和波形的全极化补偿方法、装置、设备和介质。首先测量和计算同时全极化测量体制雷达系统的交叉极化隔离度和正交波形隔离度，然后利用该雷达系统探测目标，根据回波结果获得目标极化散射矩阵的估计值，最后根据隔离度指标构建系数矩阵，利用系数矩阵对极化散射矩阵的估计值进行补偿，以获得目标
