基于改进粒子滤波的运动平台定位算法

Modified Particle Filter Approach for Target Position Location on Moving Platform

研究了运动平台对辐射源目标的定位问题。该问题是一个典型的非线性问题,因此很多定位算法对目标位置初始值的选择比较敏感,甚至造成运算结果不收敛。为解决这个问题,首先提出了一种最小均方误差预滤波改进粒子滤波算法,并将改进算法应用于运动平台对辐射源目标的定位,取得了比较好的效果。

The problem of emitter target location was considered using a moving platform. Because this problem is a non-linear problem,many position algorithms are too sensitive to the initial coordinate value of emitter target. The accurate position is difficult to estimate. To solve this problem,a modified particle filter approach based on Minimum Mean Square Error was proposed. Then the modified method was applied on the problem of emitter target location. Its performance is better in the simulation.
