相控阵雷达接收通道校准方法仿真

Simulation on the method of receiving channel calibration for the phased array radar

接收通道校正是保证接收波束形成性能的重要环节。构建了内场校准和外场校准相结合的通道校准方法的仿真模型。仿真结果验证了该方法可以明显改善第一副瓣水平,减小幅相误差对系统性能的影响。

The receiving channel calibration is an important link to ensure the performance of receiver beam forming. A simulation model is composed on the method of channel calibration consisted of the combination of internal field calibration and external field calibration. The simulation result shows that this method is capable of improving the first side-lobe, and reducing the influence of amplitude-phase error on the performance of the system.
