针对载机平台上的激光目标指示器照射过程的动态响应及其模拟,利用高斯白噪声,通过由滤波器产生的有色噪声的方法模拟了目标指示器指示激光光斑抖动信号的统计平均特征,分别进行了抖动光斑位置随时间变化和在简化地物模型下漫反射信号强度随时间变化的动态模拟以及实际验证测试。经分析表明:在载机平台上,激光动态照射过程中的反射信号强度的变化是与平台相对于目标运动、目标表面的漫射特性和反射特性等因素相关的综合函数;基于二阶振动系统响应模型的方法可应用于激光目标指示器照射过程中的激光制导信号的大气传输和探测的动态模拟。
Aiming at the dynamic response and its simulation of laser target indicator irradiating on carrier platform, Gaussian white noise is used to simulate the statistical average characteristic of laser flaw jitter signal of target indicator through the method of colored noise generated by the filter. The dynamic simulations and actual verification tests of the change of the position of the dithering spot with time and the intensity change of the diffuse reflection signal under the simplified feature model were carried out. The analysis shows that on the aircraft platform, the change of the reflected signal intensity during the dynamic laser irradiation is an integrated function related to the platform relative to the target movement, the diffusion and reflection characteristics of the target surface. Based on the second-order vibration system The response model approach can be applied to the dynamic simulation of atmospheric transmission and detection of laser-guided signals during the irradiation of a laser target indicator.
