本文简要地介绍一种用于对独立的红外特征进行分类的被动系统。最佳硬件包括光学放大系统、红外滤光片和分光镜。探测器是一个专门设计的阵列,由两个交角为45°的十字组成,在8个径向方向上,都各自分布有16个热电探测器。分类硬件构成一个模拟并行读出和放大装置。它后面是特制的数字处理机。据以把红外特征分成为6类特性参数是:沿8个径向方位分布的探测器的输出分布、红外源表观图象的等辐射轮廊,以及在两个波长上的球面红外发射。将给出实验和模拟结果。
This article briefly introduces a passive system for categorizing individual infrared features. The best hardware includes optical amplification systems, infrared filters and spectroscopes. The detector is a specially designed array consisting of two criss-cross angles of 45 ° with 16 pyroelectric detectors distributed in each of the eight radial directions. Classification hardware constitutes an analog parallel readout and amplification device. Behind it is a special digital processor. According to the infrared characteristic is divided into six types of characteristic parameters are: the distribution of the detector along the eight radial azimuth distribution, such as the infrared source of the apparent contour of the vestibule of the vehicle, as well as in the two wavelengths on the spherical infrared emission. Experimental and simulation results will be given.
