以红外成像光学系统为例, 运用矩阵光学追迹法, 对其产生的三种回波进行研究: “猫眼效应”; “近似猫眼效应”; “剩余反射效应”。研究结果表明: “猫眼效应”和“近似猫眼效应”产生的回波概率极低, 而“剩余反射效应”的回波相对较稳定, 回波概率较高。综合利用这三种反射回波, 将大大提高探测概率。

Three kinds of echo of the infrared optical system are studied with the method of ray tracing. Research results show that the echo probability of “Cat's eye effect” and “ approximate cat's eye effect” are very low, but the echo probability of “residual reflection effect” is higher and more stable. Comprehensive utilization of these three echo, will greatly enhance the probability of detection.
