随着武器系统发展的重点转向传感器分系统,雷达和光电制导和火控系统严重地威胁飞机安全,为了提高飞机生存率,美苏等军事强国特别重视研制威胁告警系统,特别是多传感器一体化系统。所谓威胁告警包括雷达告警、激光告警和红外告警,威胁告警接收机所响应的威胁几乎只限于直接威胁飞机安全的辐射源, As the focus of weapon system development turns to sensor subsystems, radar and optoelectronic guidance and fire control systems seriously threaten the safety of aircraft. In order to improve the aircraft survival rate, the military powers such as the United States and the Soviet Union attach great importance to the development of threat alert systems, especially the multi-sensor integration system. Threat warnings include radar warnings, laser warnings, and infrared warnings. Threats to threat alert receivers respond to threats that are confined almost exclusively to radiation sources that directly threaten the safety of the aircraft,
