摘　　要：采用传统的相控阵测试方法对数字阵列及数字波束合成进行测试,存在系统复杂、设备齐套周期长、问题难解耦等弊端。因此,对于数字阵列及相关算法,需要一种不依赖天线和物理环境,且能够以低成本和高效率,在系统开发中期完成相关性能评估和迭代的方法。给出一种基于阵列信号模拟技术的低成本接收阵列方向图测试系统,并提出了随机虚拟相移技术用于解决测试精度不足的问题。基于简要的理论分析、给出了测试平台构成和测试流程,并通过仿真和实测验证了方法的有效性。Testing digital array and digital beam forming by using traditional phased array test method has some disadvantages such as complex system,long equipment cycle and difficult decoupling of problems.Therefore,for digital arrays and related algorithms,a method of evaluating and iterating on performance in the middle phase of system development at a low cost with high efficiency which does not rely on antennas and physical environments is required.A low-cost receiving array pattern test system based on array signal simulation technology is proposed,and a random virtual phase shift technique is proposed to solve the problem of insufficient test accuracy.Based on the brief theoretical analysis,the test platform composition and test process are given,and the effectiveness is verified through simulation and practical test.
