任意阵列天线自适应方向图综合的模值逼近法

Adaptive Pattern Synthesis for Arbitrary Arrays by Amplitude Approach

基于自适应理论提出了一种任意阵列天线方向图综合算法 .该算法采用模值逼近 ,并利用牛顿迭代法二次收敛的特点 ,使综合最优化方向图的速度达到非线性收敛 .该方法能够有效地控制主瓣和旁瓣的形状 。

A new pattern synthesis algorithm for arbitrary arrays based on adaptive theory was presented. This algorithm makes the amplitude of pattern approach to an object. Newton iteration method is also used so that the pattern synthesis is sped up to nonlinear convergence. The result show that not only both the main lobe and side lobe shapes can be controlled efficiently, but also the pattern approaches the expected shape more quickly.
