Abstract:

The MOS resistor array IR imaging target simulator is the most important component of hardware-in-the-loop system of the infrared imaging guidance weapon. It is used to simulate dynamic infrared target/disturbance scene. The frame frequency of dynamic image reflects the rapidity of infrared dynamic scene simulated ,is a technical index,which estimates the speed of image change of IR Target Simulator. First of all，the basic structure and the working principle of MOS resistor array IR imaging target simulator were introduced，the testing demands for frame frequency of simulated infrared radiation images in the hardware-in-the-loop IR system were discussed；Then，the testing methods of image frame frequency of simulator were put forward，and the testing platform was set up；Finally，the image frame frequency of 256×256 MOS resistor array IR imaging target simulator was tested，and the testing result was given. Conclusion：The testing method in this paper could provide some basis for the development、performance testing and application of the MOS resistor array IR imaging target simulator，and also be successfully applied to the image frame frequency of other IR imaging target simulator.
