摘要
在比较3种激光探测技术优缺点的基础上,选择技术相对成熟的光谱识别非成像型激光探测方案.针对其信号处理能力弱的缺点,采用CPLD和DSP作为信号处理芯片,通过相应的软件算法来提高信号处理能力.采用10路双通道光学系统,可实现1.06μm和1.54μm双波段、360°探测.为满足高探测概率、低虚警概率的要求,采用了二元相关探测技术.
On the basis of a comparative analysis of the advantages and disadvantages of three types of existing laser detection technology,the relative matured non-imaging spectrum recognition technology was chosen to enhance the effect-cost ratio.CPLD and DSP were applied in the signal processing chips,together with compiling of corresponding software algorithm.The 10-path dual-channel optical system can execute a 360-degree detection at the wavebands of 1.06 μm and 1.54 μm.The binary-related detection technology is utilized to maximize detection probability and to minimize false alarm probability.
