“灵巧敏感器”这一术语是指包含敏感和信号处理两种能力的敏感器,其应用对象从简单的观察直至复杂的遥感、监视、搜索/跟踪、武器制导、机器人、视感觉器和智能化等。 在广阔的敏感应用中,它们都采用复盖在整个电磁光谱上的某一种敏感器系统。本文具体论及一种在红外光谱波段工作的新型灵巧敏感器。早在几年前便开始研制这种灵巧敏感器,当时认识到,“超大规模集成化”(VLSI)处理器工艺技术和镶嵌红外探测器列阵技术的快速进步,将二者结合起来,能够研制出新一代的红外灵巧敏感器系统,其性能将得到极大的提高。 因此,在同一个焦平面上,通过把微计算机和其它超大规模集成化信号处理器集成在敏感器列阵中或附近,避免远离敏感器进行复杂计算,需要为这种新型系统发展复杂的信号处理操作运算。 最近,采用一种全新的敏感器概念,这种方法正在向更高的目标接近,这个敏感器概念把人眼的一些基本功能,如动态凝视、非均匀性补偿、空间和时间滤波等引入到敏感器中。 对于这种新型红外灵巧敏感器系统,本文给出了新型焦平面处理的新的目标和要求。本文所论及的处理技术限制于焦平面处理的前端,即通过抑制背景杂波来增强目标-噪声比以及通过“灵巧”的模式相关阈值改善对目标的探测。
The term “smart sensor” refers to a sensor that includes both sensitive and signal-processing capabilities, ranging from simple observation through to complex remote sensing, surveillance, search / tracking, weapon guidance, robotics, vision sensors, and intelligence And so on. In a wide range of sensitive applications, they all use one of the sensor systems that covers the entire electromagnetic spectrum. This article specifically addresses a new smart sensor that operates in the infrared spectral band. Developed this smart sensor as early as a few years ago when it realized that the combination of the VLSI processor technology and the rapid advancements in mosaic infrared detector array technology combined Developed a new generation of infrared smart sensor system, its performance will be greatly improved. Therefore, by integrating microcomputers and other very large scale integrated signal processors in or near the sensor array to avoid complex calculations away from the sensors, complex signals need to be developed for this new system on the same focal plane Processing operations. Recently, a new sensor concept is being introduced which is approaching a higher target. This sensor concept introduces some fundamental human functions such as dynamic gaze, non-uniformity compensation, spatial and temporal filtering, etc. Sensor. For this new infra-red deft sensor system, this article presents new goals and requirements for the new focal plane processing. The processing techniques discussed herein are limited to the frontend of focal plane processing by enhancing the target-to-noise ratio by suppressing background clutter and improving the detection of the target by “modest” mode-related thresholds.
