激光复合探测技术研究

激光复合相关探测技术是提高激光探测系统性能的有效手段。通过分析两种激光告警模式——单元探测器和成像传感器的特点，单元探测器型的灵敏度高，反应时间短，而成像型是定位精度高；明显的不足是前者定位精度低，而后者灵敏度较低，反应时间较长。对此，探索结合两种模式相结合的复合探测技术，保持两者原有的优点的同时，尽可能地克服彼此的不足，达到扬长避短，优势互补的目的。通过实验验证了该方法能有效提高系统探测性能，这对激光探测告警系统设计和优化具有指导意义。

Study on composite detection technology

Compound-related technology is an efficiency method to improve the performance of laser detection system.By analyzing the characteristics of two type laser warning system(element detector and imaging),a compounding design is presented.Laser warning and alert system based on element detector has high sensitivity and fast responding time,but its angle resolution,while imaging type system has much higher angle accuracy,but its sensitivity is low and the reaction time is long.To design a compound system which combines these two types of detection units into one will maintain the advantages of each type while overcomes its insufficiency.Experiments show that the method can effectively improve the system detection performance.The developed device has high sensitivity,fast response and good angle resolution.
