摘要
针对干涉仪测向中的基线配置问题,提出一种数值寻优设计方法,使得系统预期能够满足解模糊要求,同时对系统相位误差的容忍度又最大。以系统解模糊可容忍的相位误差最大为评价函数,采用数值仿真方法寻优,最后得到一种最优的基线组合。以几种典型的应用情况为例给出了设计流程,并采用测向仿真实验验证该方法的有效性。
A method based on numerical simulation optimization is proposed for baseline design in the interferometer direction finding system.The ambiguity solving requirements of the system could be satisfied with this method,while the maximum tolerance of the phase error is maintained.Firsly,the maximum tolerance of the phase error is considered as the cost-function.Then the numerical simulation is used for optimization.Finally,the optimal baseline can be acquired.Several typical examples are given to show the design process.After that,the direction finding simulation is also given to prove the validity of this method.
