| 摘 要： | 为了在有源干扰条件下对目标到达角精确估计,提出一种二维多通道平面相控阵雷达自适应单脉冲波束合成方法。利用平面相控阵方向图的正交性,沿阵列一个方向分别合成和子阵及差子阵,对子阵输出进行自适应处理,可以在其正交方向上形成零点,同时抑制旁瓣及主瓣干扰,并保证该方向上和、差波束不发生畸变,确保该方向的测角精度。仿真结果验证了算法的有效性。

| Abstract: | To obtain accurate estimation of target direction of arrival in the presence of electronic jamming, an adaptive digital monopulse beamforming algorithm for two dimensional multi channel phased array is proposed. Based on the orthogonality of the planar array antenna pattern, a sum subarray and a delta subarray are formed along the azimuth (elevation) direction. Through adaptive processing on subarray outputs, nulls can be formed along the orthogonal direction to suppress both mainlobe jamming and sidelobe jamming with the monopulse ratio undistorted along the azimuth (elevation) direction. Simulation results demonstrate the effectiveness of the propose method. |
