摘要
提出一种修正的配相公式,可以在只调节配相值而不改变每个阵元辐射强度的前提下形成多波束,从而实现丰富的天线波瓣形状,逼真的模拟相控阵靶标雷达天线副瓣的辐射起伏特性。根据该配相方法进行了MATLAB仿真,仿真结果验证了方法的正确性。并且,该配相方法已经在某相控阵靶标雷达研制中得到应用。
A novel amendatory phase formula is put forward, which forms multi-beam by changing the phase values without modifying the radiate intensity of each radiate cell, so as to realize a plenty of antenna lobe forms. With this formula, the side lobe fluctuation property of the phased array target radar can be realistically simulated. According to the formula the simulation by MATLAB was preformed, and the validity of the formula was proved by the result of simulation. The amendatory phase formula was put into application in certain project of phased array target radar.
