Infrared decoy simulation based on MOS resistance array

In order to verify the performance of infrared guidance missile against infrared decoy, it is necessary to simulate the energy change and motion form of infrared decoy in the actual IR scene in the process of hardware in the loop simulation, that is the variation of the radiation of the infrared decoy and separation of bait with target after the interference was deliveried. For this reason, the infrared decoy simulation was studied by using MOS resistor array. Existing domestic MOS resistor array is not less than 200 Hz refresh frequency, and equivalent blackbody temperature of not less than 300℃ can reproduce well the energy of infrared decoy changing when it is burning, at the same time, the simulation model was established based on the infrared decoy modeling theory, and the infrared decoy motion model was modified based on the collected data in the field, it is mainly infrared decoy trajectory correction. Finally, the simulation of infrared decoy was realized based on MOS dynamic infrared scene rendering and driving software.
