摘要 端射阵列雷达是新体制雷达发展的一个重要趋势,因其具有低剖面和定向辐射特性,特别适合用于机载雷达的补盲。但由于端射阵天线方向图的特殊性,其主瓣宽度比相同天线尺寸的侧射阵宽得多,这势必会导致传统自适应单脉冲测角方法性能下降。本文提出了一种基于三维空时联合约束的自适应单脉冲测角方法,将传统自适应单脉冲测角问题扩展到俯仰-方位-多普勒三维空间,利用三维杂波特性克服波束过宽所带来的问题,并可同时测出目标的方位角和俯仰角,表现出较为优越的角度估计性能。计算机仿真结果验证了该方法的有效性。 End-fire array radar is an important trend in the development of new system radars.Because of its characteristics of low profile and directional radiation,it is especially suitable for blind compensation of the airborne radar.However,due to the particularity of the antenna pattern,the beamwidth is much wider than that of the side-fire array with the same antenna size,which will inevitably lead to the performance degradation of the traditional adaptive monopulse angle estimation method.An adaptive monopulse angle estimation method based on three-dimensional space-time joint constraints is proposed.This method extends the traditional adaptive monopulse angle estimation problem to elevation-azimuth-Doppler three-dimensional space,overcomes the problem caused by wide beam by using the three-dimensional clutter characteristics and can estimate the azimuth and pitch angle of the target simultaneously,which shows superior angle estimation performance.Computer simulation results verify the effectiveness of the proposed method.
