旁瓣对消中辅助通道HT变换法对干扰源数目的判别

Using Auxiliary Channel HT Transforms to Identify the Number of Jamming in Sidelobe Cancellation

在旁瓣对消系统算法的发展历程中，“均方域算法”和“数据域算法”都有所应用。一般的方法均是在辅助通道上进行统一的“开闭”处理。本文通过对所使用的数据域方法之一的辅助通道ＨＴ 变换法的数乘特性的推导，证明了该方法能够判别空中不相关干扰源的数目并给出计算机模拟结果。这一特性的运用将使辅助通道的开闭具有自适应能力。

In the history of sidelobe cancellation algorithms,both “Power Domain”and “Data Domain” methods had been used in various scenario,most of which chose the same open or close operation to each auxiliary channel.In this paper we have proved that as one of the Data Domain methods—Auxiliary Channel HT has the capability to identify the number of uncorrelated jamming by the way of bearing out its linear property,and provided the corresponding computer simulation result.Using this capability will make the state of each auxiliary channel adaptive and will increase the performance of sidelobe cancellation system.
