摘　　要：详述了米波稀布阵雷达自适应旁瓣对消工作原理,米波稀布阵综合脉冲孔径雷达(SIAR)是一种新型米波分布阵体制雷达,采用稀布阵列天线,通过各个阵元全向发射正交编码频率信号以使各向同性照射,在接收端通过DBF和发射脉冲综合形成接收和发射波束。采用最小均方准则(LMS)对米波稀布阵雷达的抗干扰性能作了仿真,根据试验实测数据进行分析,取得了良好的干扰抑制效果,并分析比较了点频单个干扰源和多个干扰源对消处理效果,具有较强的工程实用价值。The operation principle of meterwave sparse array synthetic impulse and aperture radar （SIAR） adaptive sidelobe cancellation is described in detail in this paper. As a new type of meterwave distributed array radar, the meterwave sparse array SIAR adopts sparse array antenna. It realizes omni-direction uniform radiation in the way that each array element transmits orthogonal coding frequency signals, then the receive beam and transmit beam are formed through DBF and transmit pulse synthesizing at the receiving end. In this article, LMS is used to simulate anti-jamming capability of a SIAR. After analyzing the real data collected, excellent jamming suppression result is obtained. Cancellation processing result for single jamming source and multiple jamming sources of point frequency is analyzed and compared.
