Abstract: Aiming at tracking maneuver target of ground radar system of aerial defence and tracking，this paper will be the same with constant velocity model of constant velocity sport mode，constant accelerator model and wheel model compose former collection of wheel sport mode，tracking maneuver target by iteracting multiple model algorithm.Compared with simulator result，two kinds of combination capability are fine，not only precision tracking the sport form of target，but have good astringency and stability，it have definite value of engineering appliance.

Key words: constant velocity model, constant accelerator model, iteracting multiple algorithm, maneuver target

摘要： 针对地面防空警戒和跟踪雷达系统机动目标的跟踪，将适用于常速运动模式的常速模型，常加速运动模式的常加速模型和转弯运动模式的转弯模型组成模型集，使用交互式多模型算法对机动目标进行跟踪。仿真结果表明，其中的两种组合性能很好，不仅能够精确跟踪到低空机动目标的运动形态，而且具有很好的收敛特性和稳定性，具有一定的工程应用价值。
