摘要
讨论了多基站无源雷达的时差和多普勒频移定位算法。给出了时差和多普勒频差联合定位算法,并应用基于Gauss-Newton的批处理方法进行求解,提高定位精度。仿真结果表明,时差-多普勒频移联合定位对定位精度的提高有效可行,也克服了时差定位解模糊的问题。
An effective method for passive target tracking is proposed.This method is based on TDOA-Doppler Joint esti- mation,and solves problem by using batch data processing and gauss-newton method.Simulation results show this hybrid method can effectively achieve better performance than TDOA and can eliminate the location ambiguity.
