摘要
本文提出的基于红外面阵焦平面探测器的红外搜索跟踪系统与基于红外线线阵焦平面探测器的相比,其结构简单、成本低且具有自动搜索、跟踪和确认威胁目标的功能。本文重点论证了在全方位红外警戒系统中使用面阵探测器的可行性;在该分析的基础上,给出了该系统的图像退化模型;论证了在全方位搜索系统中,目标检测算法的处理思路,并分析了使用面阵探测器的优势。并且通过实验结果,证明基于面阵探测器的红外搜索系统是具有和线阵系统相当的目标探测距离,可以检测出信噪比在2左右的目标;并且在背景杂波处理上,在一定程度上优于线阵探测器。
The infrared search and track（IRST） system based on the area infrared focal plane array（AFPA） detector proposed in the paper has simple structure,lower cost and the same functions of autonomous search,track and confirming threat target as compared with that based on the linear infrared focal plane array（LFPA） detector.The feasibility of using AFPA in omnidirectional infrared warning system was demonstrated;based on the demonstration,the point scattering function（PSF） of degradation model images blurred by AFPAs＇ rotations was presented;the train of thought of processing the target detection algorithm was demonstrated and the advantage of using the AFPA detector was analyzed.The experiment results show that as compared with the IRST system based on the LFPA detector,that based on the AFPA detector has equal detection distance,can detect the target within infrared image with SNR higher than 2 and is better than the former in processing the background clutter.
