Aimed at the planning problem of terminal attack for TV guidence missile, a terminal planning algorithm is put forward based on a particle colony algorithm. Firstly, factors those have influence on the entrance aim angle of missile at the end are analyzed, and a restrained model of entrance angle is established. An optimization guide line of entrance angle is proposed, and an optimization model of terminal planning is built up based on a particle colony algorithm. At last, simulation and analysis are carried out, the results show that the use of this algorithm can obtain a rapid convergence and find the optimization guide line value and angel can be obtained. The validity of each model is verified adequately, and this provides an effective means for the campaign use and planning of TV guidence missile.
