• From the result we get the following conclusion : for narrow - band signal , the effect of the method based on fft is best . for wide - band signal , when snr is up to certain degree ( higher than - 7db or so ) , the curves of square error of modified methods are more obvious and closer to crb . for an echo composed of more than one frequency or direction , space - frequency distribution could show more direct information of frequency and direction , which is more advantaged to make precise judge and estimation for doa of echo
  从估计结果发现，对于窄带回波信号，基于fft的方法估计性能大大优于其他方法；对于宽带回波信号，在信噪比达到一定程度(高于约- 7db )时，补偿后的几种估计法的性能改善均比较明显，误差曲线越来越接近crb曲线；对于回波中存在多频率多方位的情况，空间?频率分布图能提供较为直观的频率及方位信息，因此应用空间?频率估计法来进行方位估计，更有利于进一步对回波的具体方位进行准确判断和估计。
