对于低空、超低空飞行的威胁目标(导弹、飞机),红外警戒系统是一种有效的、发展迅速的近程防御与对抗武器装备。针对红外警戒系统的主要技术,提出了系统的战术技术要求;分析了信号处理对系统作用距离的影响;给出了一种红外点目标信号预处理方法和红外目标点迹处理方法,以及虚警时间、虚警概率、探测概率的关系;探讨了双波段数据融合技术并简述了系统的研制现状及发展趋势。
For low-altitude, low-altitude flight threat targets (missiles, aircraft), infrared warning system is an effective, rapid development of short-range defense and counter weapons. Aimed at the main technology of infrared warning system, the tactical and technical requirements of the system are put forward. The influence of signal processing on the system operating distance is analyzed. A method of infrared point target signal preprocessing and infrared target point tracking is given, Time, false alarm probability and probing probability. The dual-band data fusion technology is discussed and the research status and development trend of the system are also briefly described.
