红外成像导引系统抗干扰性能评估研究

摘要

为解决红外成像导引系统抗干扰性能难于定量评估问题,给出了一种新的评估指标体系.首先通过详细分析红外光学系统、调制器、探测器、图像处理系统、陀螺伺服系统的性能参数,得到红外导引系统在抗干扰过程中的固有性能指标；然后规划了在不同仿真条件下的抗干扰仿真实验,得到抗干扰识别算法概率和各种干扰因素的数据；最后采用层次分析法建立了红外成像导引系统抗干扰性能计算模型,并用算例进行了计算,结果表明该指标体系具有一定的实用性.%In order to improve the evaluation precision of anti-jamming performance of IR Imaging Guidance Systems (IRIGS), a new set of evaluation index system was given. Firstly, the performance parameters of infrared optical system, modulator, detector, image processing system, gyro servo system were analyzed, and the inherent performance index of IRIGS in anti-interference was gained. Secondly, the anti-interference simulation experiment under different simulation conditions was programmed, and the values of anti-interference recognition algorithm probability and various interference factors were obtained. Finally, the antijamming probability models of IRIGS were established by using Analytic Hierarchy Process ( AHP). An example indicated that this index system is practical.
