摘　　要：针对工程实践中数字多波束形成方法的正确性不易验证,提出了一种基于方向图测试的数字多波束形成验证方法,模拟4个不同方位、俯仰的固定目标,利用天线对其进行方位、俯仰多层扫描,获取水平方向图和俯仰方向图。结果表明方向图测试法能够验证数字多波束偏移角度与权值系数的正确性,较好地解决了工程中数字多波束形成验证问题。Aiming at the problem that the correctness of digital multi-beam forming method is not easy to be validated in the engineering practice, this paper presents a validation method of digital multi-beam forming based on directional pattern test, simulates 4 fixed targets with different azi- muth angles and elevation angles,performs the azimuth and elevation multilayer scanning by using antenna to obtain the horizontal and elevation directional pattern. Results show that the directional pattern test method can validate the correctness of offset angle and we multi-beam, which can solve the validation problem of digital multi-beam ight coefficient of digital forming in the engineering practice.
