摘　　要：首先对稀布阵雷达系统特点和副瓣性能进行分析,指出雷达在远场和近场均可能存在各种干扰,而稀布阵雷达副瓣水平相对较差,故干扰方位指示功能有其特殊性。然后结合稀布阵雷达工作特点,对其常规方向指示算法对多干扰定位的局限性进行分析。最后提出采用聚焦波束结合特征值分解的方法对干扰方向进行估计的方案。本文结合了实际近场静态数据及远场干扰源飞行数据对方案效果进行验证,取得良好的效果。The sidelobe performance of synthetic impulse and aperture radar（SIAR） is discussed,and particularity of such system is pointed out.The analysis of the conventional process shows that the direction of arrival（DOA） of muti-interference is a difficult problem for SIAR system.Therefore,a novel method combining focused beam-forming and eigenvalue decomposition is presented,and the DOA performance is researched based on the experimental data.Result shows that the direction of the interference can be measured accurately by using this method.The work is important to design and application of the SIAR system.
