Simulated signal source for four-element infrared detection system - simulation of the target detection signal

For the inspections required during the development and production of infrared homer, the simulation technologies for the output signal from four-element detection system are investigated. The dynamic processes under multiple targets and interfering conditions, such as the target movement from far to near in the system field of view and the launching of disturber, as well as the output signals from image discs scanning along the scanning circle on the cross pattern IR detector can all be realized in the computerized simulation, and both the amplitude and phasic relationship of the output signals are well simulated. The above simulation technique is important and practicable in the development of the new IR homer technology.
