激光探测目标仿真算法研究

Study of simulation algorithm on target detection by laser

提出了激光雷达、激光引信等激光探测系统的目标、背景反射特性仿真算法。建立了海浪背景和一般目标的数学模型及其验模。从统计学的角度推导了海浪的激光反射特性及激光反射能量随入射角的变化关系，给出补偿方程，同时为保证海浪反射特性模型精度及目标反射特性模型精度，采用最小二乘法的验模方法修正模型，使模型精度达到指标要求。

A novel simulation algorithm is shown in this paper, which can be used to study the reflective characteristic of targets and background of laser detection system, such as laser radar and laser fuse. And the mathematic model of seawave background and general targets is established, as well the verification of this model. From this mathematic model the relationship between the laser reflective characteristic and reflected energy of seawave and the incidence angle is derived by the statistical method, and the compensation function is also given. And then using least square, a correction model of model verification and procedure is also shown, which guarranteed the model accuracy of the laser reflective characteristic of seawave and targets, and fulfiled the feature requirements.\=\;
