Low-cost Test System and Method of Receiving Array Pattern
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 decou-pling 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 effi-ciency 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 ef-fectiveness is verified through simulation and practical test.
