摘要
对于起降阶段的各类飞机来说,便携式导弹是主要威胁。以基于Ⅱ类超晶格双光谱红外探测器的机载导弹逼近告警(MAW)系统为应用背景,介绍了光谱串音的定义及计算方法。分别测出两个光谱通道的光谱响应曲线,容易利用MATLAB样条函数积分命令算出两条曲线交叉部分围成的面积,该面积的数值反映了器件光谱串音的大小。给出了所用MATLAB程序,该方法具有实现容易、使用快捷等特点。
The main threats for any type of aircraft are the man portable missiles during taking-off and landing.Under the application background of missile approach warning（MAW） based on type Ⅱ superlatice bispectral infrared detectors,the definition and calculation methods of spectral crosstalk were introduced.After measuring separately the spectral response curves of the two spectral channels,the area of the region bounded by the crossed sections of the two curves reflecting the amount of spectral crosstalk of the device,can be calculated easily with MATLAB spline function integration commands.The MATLAB program was listed in this paper.It is easier to implement and convenient to use.
