Problems solved by technology

First, the development and procurement of infrared detectors will affect the development progress of the infrared image acquisition and processing system; second, because the system test cannot be completed successfully at one time, it is necessary to insert and pull out the detection device multiple times to test the performance of the system. It will bring risks to the detection device; third, the uncertainty of the function of the front-end optical path system will lead to the uncertainty of the test of the back-end infrared image acquisition and processing system

Fourth, the acquisition of infrared images takes a long time and a lot of manpower and material resources. In addition, it is difficult to obtain infrared images under various weather conditions, and it is also difficult to capture infrared images of many military targets.

First of all, most of them are simply designed for the consideration of providing image data sources for the infrared signal processing platform, without considering the simulation of relevant infrared parameters (such as noise parameters); secondly, the versatility is poor, and the detector parameters can be changed. The adjustment ability is limited, such as the narrow dynamic range of analog signal output, less selectivity of array scale, non-adjustable output frequency, no synchronous output of image data and other defects; and the existing infrared imaging detector simulators are all fixed computer hosts equipped with data processing platforms It is inconvenient to implement the function of the simulator, and it does not have the characteristics of integration
