设计了采用CO2激光器作为激光辐射源的10.6μm激光驾束制导仪激光编码调制器。利用频率编码调制技术,提出系统参数能满足该制导仪的编码方式和光学调制码盘。根据制导控制要求,通过计算偏离中心的数学模型,给出了合理的编码频率。由频率和调制码盘的尺寸,得出了每个部分的光栅数量和宽度,以满足高速飞行器激光驾束制导的应用需要。激光编码调制器的各参数设计合理并满足制导仪精度的要求。
A 10.6μm laser beam steering laser code modulator with CO2 laser as laser radiation source was designed. The use of frequency coding modulation technology, proposed that the system parameters to meet the guidance of the encoder encoding and optical modulation code disc. According to the guidance control requirements, a reasonable coding frequency is given by calculating the deviation from the center of the mathematical model. From the frequency and the size of the modulation code disc, the grating number and width of each part are obtained to meet the application requirements of laser beam steering guidance for high-speed aircraft. The parameters of the laser coded modulator are designed reasonably and meet the requirements of the guide instrument accuracy.
