【摘要】 本文分析空间光通信平台振动功率谱,发现振动功率主要集中在几个尖峰点附近,用振动功率谱设计滤波器方法生成了通信平台振动数据。以量子理论为基础,把激光能量和各种CCD噪声都转换为等效电荷,在此基础上建立了CCD光斑检测模型。假设大气湍流为弱起伏湍流,用高斯噪声模拟了大气湍流的影响。对APT跟踪子系统各器件的输入输出关系及其特性进行简化,建立其仿真模型。对以上模型都给出了计算机实现算法。提出了基于HLA的层分布式仿真系统设计,并实现了分布式协同仿真。给出了一种对仿真系统可信度进行半实物检验的方法。
【Abstract】 In this paper, we analyzed the power spectral density of optical communication platform and found that the power of vibrancy was mainly concentrated at several peaks. So we use the method of filter designed according to power spectral density to produce the vibrancy data of optical communication platform. On the basis of the quantum theory, the optical energy and various noise of CCD could be converted to equivalent electric charges, and then the facular detection model of CCD was proposed. The atmosphere turbulence was seen as weak fluctuation turbulence, and Gaussian noise was used to simulate influence of atmosphere turbulence on transmission of laser beam. The I/O relation and characteristics of tracking subsystem of APT were simplified, and then its model was established. The arithmetic of the above models was also proposed in this paper. A distributed simulation system of APT which based on HLA was proposed in order to realize distributed collaborative simulation. A method of hardware in loop evaluation on the credibility of simulation system was proposed.
