摘要
为评估激光告警散射截获半径的边界,根据激光告警系统的散射告警原理,基于米氏散射理论,推导出适于工程应用的波长1.064μm激光告警离轴散射探测模型。分析了激光告警探测系统的主要噪声源,提出了基于激光告警阈值探测理论的散射截获半径评估方法;利用编程工具MATLAB对某激光告警系统的散射截获半径边界进行了仿真计算。
In order to evaluate the boundary of scattering interceptive range for 1.06μm laser warning devices,accord-ing to the scattering warning principle of laser warning system,off-axis scattering detective model of laser warning was deduced based on Mie scattering theory.Then the main noise sources of laser warning system were analyzed,and the method for evaluating scattering interceptive range was proposed based on the principle of laser warning threshold de-tection.Finally,the boundary of scattering interceptive range of a certain laser warining system was simulated and cal-culated by MATLAB software.
