Baseline Configuration Design of Interferometer Direction Finding System Based on Virtual Baseline

通过外场应用条件下基于虚拟基线的多基线数字干涉仪设计、仿真,阐述了实际工程应用中,在工作频率范围、测向精度和相位差测量精度等约束条件下,如何设置天线阵列基线的问题,给出了不同基线配置间逐级解模糊的条件及基于虚拟基线配置方法的组阵设计依据,并验证了该方法的有效性。

Taking frequency, accuracy of direction finding and accuracy of phase difference into consideration, this paperintroduces the method of defuzzification step by step and proposes the baseline configuration design of interferometer directionfinding system based on virtual baseline. At last, it carries out the simulation experiment and proves that the baselineconfiguration design can solve the problem of antenna array arrangement in multi-baseline digital interferometer effectively.
