In this paper, the method of testing the amplitude and phase characteristics of the infrared target signal in the infrared target tracking and detection system and the tracking phase and the application of the domestic integrated multiplier in the infrared target tracking system such as automatic increase control and infrared target simulation are described. Taking the infrared tracking system SM-7 as the target of airspace aircraft as an example, the paper first analyzes the Archimedes’ spiral optical pulse width modulated disk. Then the principle and method of testing the dynamic characteristics of the infrared detection system, amplitude and phase characteristics, are expounded. Finally, by using the target simulation device and the amplitude and phase characteristics test method proposed in this paper, the tracking circuit of the AGC and other functions completed by the domestic integrated multiplier instead of the Soviet SM-7 system is tested. Some experimental reference data charts are given. The simulation method mentioned in this paper is applied to different regions of the target pixel after the simulation of pulse infrared signal generated by the spiral disk. By adjusting the electrical signal amplitude, phase, frequency and other parameters can be easily simulated. The article put forward
