The Passive Target Motion Parameters Estimate Algorithm Based on Particle Filter

摘要

A new passive target motion analysis (TMA) based on method a single seismic-filed vector sensor is designed using pitching angle and multi-path delay is studied. The state equation and measurement equation are established and analyzed systemically by improvement particle filter based on the measurements of both bearings and time delay that are collected by the sensor. The Monte Carlo simulation experiment results demonstrate that the algorithm has some advantages of fast convergence, high precision and stability.
