In this thesis , passive location algorithms based on particle filter are discussed and monte carlo experimental results prove effectiveness of those algorithms . regarding different scenarios the following part of the thesis is arranged as follows . in the first chapter , background and current situation in location and tracking are briefly introduced 本文研究利用粒子滤波技术实现基于测向信息的单站无源定位的技术,并在此基础上融合距离信息后,提出一种快速的无源定位粒子滤波算法,通过计算机仿真,验证了该算法的有效性和优越性。
