IMM算法，用于机动目标的精确跟踪和定位，该模型集考虑了三种典型子模型:CV,CT,CA.-interacting multiple model (IMM) code for target tracking

采用组合权重的交互多模型算法，实现基于KALMAN滤波的而模型滤波，并与常规IMM算法对比。(The model is filtered by the KALMAN filter based on the interacting multiple model algorithm with combination weights, and compared with the conventional IMM algorithm.)
