SATKA是Surveillance(监视)、Acquisition(捕获)、Tracking(跟踪)和Kill Assessment(摧毁评定)的缩写。在“星球大战计划”中,称为对目标进行监视、捕获、跟踪和摧毁评定的功能,或是为实现此目的的传感系统。换句话说,其功能是迎击来袭弹道导弹时,取得早期预警和判断进攻特性,给作战管理和迎击武器系统指定目标,以及判定迎击效果等所必需的目标信息。还包括从伪装等非威胁目标和自然背景中,识别出真正威胁性目标所需的信号处理和数据处理功能。早期预警和攻击判断功能,原先是由北美空间防御司令部所管辖的弹道导弹监视体制(早期预警卫星DSP、BMEWS雷达网)和宇 SATKA is an acronym for Surveillance, Acquisition, Tracking and Kill Assessment. In the Star Wars Project, it is called the ability to monitor, capture, track, and destroy a target, or to provide a sensing system for this purpose. In other words, its function is to meet the target information necessary for early warning and judgment of offensive characteristics against incoming ballistic missiles, for designating targets for combat management and combat weapons systems, and for judging impact. It also includes the signal processing and data processing functions required to identify truly threatening targets from non-threatening and natural backgrounds such as masquerading. Early warning and attack judgment capabilities, originally by the North American Space Defense Command under the jurisdiction of the ballistic missile surveillance system (Early Warning Satellite DSP, BMEWS radar network) and Yu
