分布孔径红外系统(DAIRS)是目前军事强国在红外搜索跟踪系统领域的重点发展方向。作用距离是DAIRS最重要的参数指标之一，其大小由系统参数、目标和背景特性等决定。针对DAIRS的成像与信息处理特点，对系统的作用距离进行了研究，建立了DAIRS作用距离模型，分析了目标方位、探测器积分时间和瞬时视场等因素对DAIRS与传统扫描型系统作用距离的影响。该模型对DAIRS的设计具有一定的参考意义。

Distributed Aperture Infrared System (DAIRS) is the trend of infrared search and track system of military powers. Operation range is one of the most important parameters of DAIRS, which is decided by system parameters, features of target and background, etc. The operation range based on the characteristics of imaging and information processing of DAIRS was studied in this paper. A mathematical model of operating range for ground-based DAIRS was established, and the influences of target orientation, detector integration time, and instantaneous field of view(IFOV) on operation range of DAIRS and traditional scanning imaging infrared system were analyzed. The mathematical model is helpful to the design of DAIRS.
