| 摘 要： | 目前红外搜索跟踪(IRST)系统普遍采用红外焦平面传感器,线阵FPA使系统达到了更高的灵敏度和分辨率.然而由于线阵FPA扫描系统的固有限制,IRST系统不能实现任意方位的潜在目标跟踪,而采用面阵FPA的IRST系统可以较好的解决这些问题,但帧积分时间内探测器的扫描运动使图像存在严重的拖尾,给目标探测带来了影响.介绍了一种基于面阵FPA的全方位红外预警系统设计,并对采用线阵和面阵FPA探测器的系统性能进行了对比分析.提出通过目标能量累积技术弥补目标拖尾对面阵FPA扫描系统探测性能的影响,实验验证了能量累积技术可以使面阵IRST达到接近线阵IRST的探测距离,同时具有更低的虚警率.

| Abstract: | Infrared search and track(IRST) system is a wide field of view surveillance system for autonomous search,detection,acquisition,and cue of potential targets.With improvment of infrared focal plane array sensors,now,IRST utilize line focal plane array(FPA) sensors to achieve higher sensitivity and resolution.However,due to inherent limitations of line FPA sensors,IRST with scanning line FPA cannot be stopped at any desired position to scan a small sector of interest.They also suffer from more false alarms in ... |
