为了发挥红外技术的优点和开发高技术的更多应用,如红外制导、火控、跟踪、成像以及预警系统等,本文描述了红外搜索系统及其主要参数,如瞬时视场、搜索视场、扫描速率、带宽、扫描效率、探测概率、信噪比、搜索距离等。红外搜索系统在国外已相当发展并应用于某些领域。但在我国仍属空白。预计不久的将来,随着激光对抗武器和目标侦察系统的需要,将会迅速地发展。 In order to give full play to the advantages of infrared technology and develop more high-tech applications such as infrared guidance, fire control, tracking, imaging and early warning systems, this paper describes the infrared search system and its main parameters such as instantaneous field of view, Scan rate, bandwidth, scan efficiency, detection probability, signal to noise ratio, search distance and so on. Infrared search system has been quite developed abroad and applied to some areas. However, it is still blank in our country. It is expected that in the near future, with the demand of laser weapons and target reconnaissance systems, there will be rapid development.
