在飞行目标的靶场试验中，需要对其进行有效的检测、跟踪和精确地完成位置估计.在分析激光跟踪测量系统和红外搜索与跟踪系统的发展现状、工作原理、发展趋势的基础上，提出一种新的基于激光跟踪测量系统和红外搜索与跟踪系统异构传感器的融合模型，对飞行目标在靶场试验的过程中进行数据融合，从而得到更为精确的飞行位置数据.

In testing a flying object in the range,the detecting, tracking and estimating of the position of the object are necessary.After analyzing laser tracking and measurement system and infrared search and tracking system’s the development now, work principle and development trend, a new data fusion model based on LTMS and IRST was put forward. The fusion model can be used to make data fusion during the flying object test in the range in order to obtain the more precise data about the flying object position.
