| 摘 要： | 舰载雷达情形下进行阵列信号处理时，通道幅相不一致性导致分辨算法性能严重下降，本文通过在接收机前端加模拟信号源，在经过距离与速度分辨后，对回波数据进行了有效补偿。通过补偿前后空间谱估计效果的对比，可以看出数据补偿使算法的分辨精度得以提高，达到了数据补偿的目的。

| Abstract: | In signal processing of shipborne radar, in the presence of amplitude and phase errors of different channels, the performance of high resolution algorithm degrades significantly. In this paper, by setting a simulation signal source before the receiver, the echo data are compensated effectively after range resolution and velocity resolution. By comparison of spatial spectrum estimates before and after compensation, we can see that data compensation makes the resolution improved. |

| Keywords: | shipborne radar amplitude and phase discordance high resolution algorithm |
