Simulation analysis of the angle tracing system for infrared imaging seeker

A linear mathematical model is built according to the operation principle of infrared imaging seeker angle tracing system.The modeling simulation and analysis is focused on the performance of the tracking loop,the influence of the parameter variety,the performance of the tracking loop when considering the shooter model,and isolation degree of the test.The simulation result indicates that the performance of the tracking loop of the seeker already satisfy design specification.And the seeker has the good anti-interference ability.Finally,the optimization way of the seeker angle tracing system is presented.It provides the reference for determination of total project and design of total parameters of infrared guided missile system.
