Hardware-in-the-loop Simulation of Infrared Seeker Based on Direct Signal Injection

A "direct signal inject" method for hardware-in-the-loop simulation of four-element infrared seeker was proposed.Infrared scene comprised of target, countermeasure and background signals can be directly injected into the electronic cabin of seeker for verification and modification of the algorithms of tracking and anti-jamming.The architecture design of the simulation system was discussed in detail,and the modeling of target movement,interference missile and complex background scene was investigated.The dynamic infrared scene generation techniques were studied based on the four-element infrared seeking principle.And finally the implementation of the hardware-in-the-loop simulation system was given.
