【摘要】 多波束天线广泛应用于现代雷达通信探测系统中。目前大部分的多波束形成方法,都是通过子阵波束叠加或者按一定频率切换波束指向来实现多目标区域的覆盖,介绍一种基于NLMS算法实现多波束形成的方法。阵列天线在不需要子阵的情况下可同时形成多个波束,并能够对副瓣进行控制以及产生目标零陷。同时,进一部对多波束形成各方法进行了综合的分析和比较。设计者通过该方法可以进行有效,灵活的对任意阵形天线实施所要求的多波束形成。实验仿真结果表明该方法的可行性,有效性以及实用性。更多还原

【Abstract】 Multi-beam antennas have found widely use in modern radar communications and detection system. Most existing methods for multi-beam forming,by beam forming in the sub-array respectively or switch the direction of beam according to a certain frequency to realize multi -area coverage.The paper presents a methord for multi-beam forming based on NLMS algorithm.The methord can make the array antenna produce multi-beam simultaneously out of sub-array.Further more,it can be sidelobe controling and make the nulls aim at the jammer.In comparison to other methords for multi-beam forming,it can produce the required multi -beam effectively and flexibly.Example simulations are shown to illustrate the feasibility and practicability of the methord.更多还原
