强干扰环境下性能优化的相互作用多模型-概率数据关联算法

THE ADVANCED IMM-PDAF ALGORITHM IN A HEAVY CLUTTER ENVIRONMENT

在大区域空中交通管制 ATM(Air Traffic Manage)调度多批次飞机时 ,由于各种干扰和虚警的存在 ,致使相互作用多模型 -概率数据关联算法 (IMM- PDA)的性能下降 .为此 ,提出一个新颖的算法 ,即利用某些先验概率知识构造一个判断回波有效性的函数 ,通过该函数来估计无效回波、并将其排除在外 ,从而改善了算法的性能 .最后 ,通过仿真给以验证 .

The performance of IMM-PDA algorithm can be decreased due to all kinds of clutter and false alarms during managing lots of planes in large region air traffic manage ment(ATM). Hence, a novel algorithm is presented in this paper, that is, a function appraising the performance of IMM-PDA is set up with some prior probabilities measurements caused by clutter or other targets can be estimated efficiently and filtered out via this method, Then the performance of IMM-PDA is improved. At last, simulation for verification of the algorithm is given.
