前言如资料[1～3]所述,可用最佳空间滤波和选择最佳工作波长的办法来改善被动式红外探测跟踪系统的信噪比。可是,对于受太阳光影响强烈的天空和城区街道背景来说,用原来的探测系统时,即便采用最佳工作波长,也不会得到很高的信噪比,因此,作者等致力于研究新的探测方式。本文提出的交叉相关探测法,就是其中的成果之一。在此以前的探测方式都只利用一个波段,而若采用多个波段(本文采用二个波段的组合),利用它们的交叉相关处理,
Preface As described in [1] to [3], the best spatial filtering and selection of the best working wavelength can be used to improve the signal-to-noise ratio of passive infrared detection and tracking systems. However, for the sky and urban street background strongly influenced by the sunlight, when the original detection system is used, the high signal-to-noise ratio can not be obtained even when the optimal working wavelength is adopted. Therefore, the author is devoted to researching new The detection method. Cross-correlation detection method proposed in this paper is one of the results. In this previous detection methods are only one band, and if the use of multiple bands (in this paper, a combination of two bands), the use of their cross-correlation processing,
