| 摘 要： | 相控阵天线要实现宽带处理一直是一个难题，带宽宽天线波束指向会发生偏移，由于孔径渡越会引起信号发生畸变。通过对带宽影响的机理分析和无源测向机理的分析，提出了一种宽带有源相控阵测向实现方法。利用该方法可以在一定工程可实现的边界约束条件下完成宽带相控阵测向。

| Abstract: | Recently, phased array antenna processing wideband signal is a big problem in the world. Wide frequency makes the antenna beam direction deviate to the expecting direction, and it also makes signal distortion because of the aperture fill problem. Through analyzing the principle of the wideband influence and elements of the passive DOA, a new wideband active phased array DOA algorithm is presented. Using this method, it can achieve the wideband phased array direction finding under certain engineering realizable constraints. |
