Infrared tracking is a very important tracking system. In order to simulate the cross-point infrared point source detection process, the space mapping, signal sampling and signal representation module are designed to simulate the complete signal generation process from the target spatial characteristics to the effective signal representation. Two new features, amplitude change rate and adaptive gate, are proposed to describe the target signal. The signal analysis and anti-interference tracking are combined with the traditional characteristics of amplitude and delay and the state transition. A complete 3-D simulation system platform is established, and the simulation of the simulation model and the tracking algorithm are also carried out. The validity of the model and the algorithm is proved.
