用于阵列处理的自适应均衡器的研究

The Study on Adaptive Equalizer for Array Processing

通道之间的幅相特性不一致性（通道失配）严重影响了雷达阵列信号处理的性能，通道均衡器是补偿通道失配的一种方法。本文研究了用ＦＩＲ滤波器实现的自适应通道均衡器的频域和时域两种算法，在通道失配模型基础上计算了频域算法通道均衡器的性能及其与一些主要参数的关系，最后讨论了频域算法均衡器实现上的一些问题。

The frequency dependent interchannel mismatch may severely degrade an array's performance unless some form of compensation is employed.The compensation can be achieved by means of a FIR equalizer.Two algorithms of the equalizer,named frequency-domain-based and time-domain-based algorithms,are investigated.A new channel mismatch model is adopted to evaluate the performance of the fre-quency-domain-based equalizer as a function of a set of parameters.Finally,some practical considerations in the implementation of the equalizer are discussed.
