美国利用卫星和传感器网络跟踪弹道导弹发射,其中包括探测地球静止轨道发射信号的天基红外系统。 The U.S. tracks ballistic missile launches using a network of satellites and sensors, including the Space-Based Infrared System (SBIRS), which detects launch signatures from geostationary orbits. 这些系统识别导弹特征,如类型和轨迹,向美国军事部队提供预警。 These systems identify missile characteristics like type and trajectory, providing early warnings to U.S. military forces. 该技术最初于1950年代开发,现已演变为包括先进的传感器和对较不严重威胁的自动警报,并对更危急的局势进行人力分析。 The technology, originally developed in the 1950s, has evolved to include advanced sensors and automated alerts for less serious threats, with human analysis for more critical situations.
