摘要

如果在雷达扫描域中应用自适应波束形成先于多普勒处理，由于自适应过程而产生的权重抖动将降低扫描相干性并导致多普勒处理不匹配。当雷达信号的某些扫频受到脉冲性质的定向干扰时，应用基于中值的估计量从中间扫频中选择波束的权值，可以改善块自适应方法的性能。本文介绍了在避免重量抖动的同时抑制脉冲方向干扰的方法。

The application of median based estimators in robust adaptive beamforming for high frequency radar

If adaptive beamforming is applied prior to Doppler processing in the radar sweep domain, weight jitters which occur as a result of the adaptation process will reduce sweep coherence and cause mismatched Doppler processing. If some sweeps of the radar signal are corrupted by directional interference of an impulsive nature, it is shown that the performance of the block adaptation approach can be improved by the application of median based estimators in selecting the weights for a beam from intermediate sweeps. This paper introduces the method for attenuating impulsive directional interference while avoiding weight jitters.
