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。 Taking the infrared imaging optical system as an example, three kinds of echoes generated by the matrix optical tracing method are studied: “Cat’s Eye Effect”; “Approximate Cat’s Eye Effect”; “Residual Reflection Effect”. The results show that the probability of echoes produced by cat and cows cats is very low, and the echoes of “residual reflection ” are relatively stable with high echo probability. Comprehensive utilization of these three reflected echoes, will greatly increase the probability of detection.
