Study of Beam-forming Based on Collaborative Subarray

针对平面相控阵天线波束响应随扫描范围扩大急剧下降的问题,提出了一种子阵协同作用的波束形成方法,通过该方法可以改善相控阵天线的低仰角性能,扩大相控阵天线的作用空域。介绍了一种子阵协同作用下的相控阵天线阵列,对其协同作用的波束形成进行了仿真分析。构建了该相控阵天线的试验测试环境,通过试验测试验证了该方法的可行性及正确性。

Aiming at the problem of planar phased array＇s beam response dropping with increased scanning range,a method of beam-forming based on collaborative subarray which could improve the performance with wide coverage angle is studied.A collaborative subarray structure is introduced and the beam-forming simulation results are analyzed. A test environment is set up,and the feasibility and accuracy of the collaborative subarray beam-forming method is demonstrated through the test.
