自适应多波束形成的算法

AN ALGORITHM FOR ADAPTIVE MULTIBEAMFORMER

论述了一种窄带和宽带多波束形成的算法,这种算法所依据的准则是在波束满足指向和振幅要求的约束条件下使阵列输出功率最小。对于 N 元阵列,可同时形成 N-1个独立波束。根据对约束条件的不同控制,利用这种算法可实现波束扫描,形成宽波束、实现干扰对消或旁瓣对消等。同时还给出了所述算法的计算机模拟结果,结果表明所述算法是很有效的。

This paper describes an algorithm for adaptive multibeamformer ofnarrowband and wideband systems.The optimal criterion which is the algorithm based onis that choising the suitable weights minimze the output power in the array output undersatisfying the constraints for the beam direction and amplitude.It is able to form N-1 inde-pendent beams for an N elements array.According to the different constraints it can prac-tise beam scanning,Widebeam forming interference canceling,sidelobe canceling and soon.The results of Computer sirnulation based on the algorithm described are given,theseresults illustrate that the algorithm described is quite available for forming multibeam.
