The Advanced IMM-PDAF Algorithm in a Heavy Clutter Environment
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 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.
