红外传感器自身效应仿真研究

在实验室里采用硬件闭环方式测试和评估红外导引头信息处理机需要实时、高逼真度的红外光电仿真技术。为了在硬件闭环仿真中更真实有效的评估导引头信息处理机算法的性能，必须在硬件闭环仿真中增加红外传感器效应自身仿真的环节。通过对红外传感器自身效应的仿真方法和需要实现的关键功能进行分析，确定了仿真功能流程。充分考虑到多种处理要求，设计了一种基于FPGA＋DSP的硬件实现方式。最后通过实验结果验证了设计方法的有效性。

Simulation Study of Inherent Effects of Infrared Sensor

The test and evaluation of IR guiding information processing system by closed-loop test in laboratory require the application of real-time, high fidelity IR/EO simulation technology. To evaluate the algorithm performance of IR guiding information processing system more effectively, a simulation module that considers the inherent effects of infrared sensor must be added into the closed-loop test. Through detailed analysis of the simulation methods and the required key functions, the flowchart of the simulation module was determined. And a hardware implementation based on FPGA DSP was proposed to meet various processing requirements. Finally, the effectiveness of the design was validated by test results.
