RGPO干扰下基于改进的IMM-PDAF的机动目标跟踪技术
A Maneuvering Target Tracking Technique Based on Modified IMM-PDAF Under RPGO Jamming
摘要
Abstract
Single maneuvering target tracking problem in clutter environment under the range gate pull of (RGPO) jamming is studied in this paper.The radar measurement model under RGPO jamming is established firstly,and then the target tracking technology under RGPO jamming based on the improved IMM-PDAF is proposed.This technique combined with RGPO jamming identification and tracking integration.In the jamming identification,the signal likelihood ratio preprocessing,angle Chi square test and m/n logic test method is adopted.In tracking algorithm term,the proposed IMM-PDAF algorithm based on the power characteristics of measurements is adopted,and different methods for state update is adopted according to whether it exist a RGPO jamming.If there is a RGPO jamming,the synthesis measurement by using proposed methods is used for target state update;If there is no jamming,all the measurements are weighted by power and position features to update the target state.Simulation results show that the proposed technique can not only eliminate the adverse effects caused by RGPO jamming,but also has good tracking performance for maneuvering target.关键词
