英文摘要：

The Infrared target tracking system is a very important tracking system. In this paper, the detection process of the cross-shaped infrared point source tracking system is modeled through space mapping, signal sampling, and signal rep- resentation. With these models, this paper describes the simulation of the whole signal generation process. Two new fea- tures, the amplitude change rate and adaptive gate, are proposed for signal description. Combined with traditional charac- teristics of amplitude and time delay, this paper provides a status transfer framework for signal analysis and anti-jamming tracking. Furthermore, a complete 3D simulation platform is built to test the simulation model as well as the tracking algo- rithm and the result proves the validity of them.
