摘要
通过对激光驾束制导原理的分析,提出了一种基于DSP、FPGA以及高精度D/A的激光驾束制导信息光场的模拟发射系统;上位机通过RS232串口向DSP发送仿真制导指令,DSP将数据处理后发送给FPGA,FPGA控制DA产生符合光信息场调制规律的电脉冲信号,通过该信号对激光器进行调制,从而获得特定的光信息场。所设计的模拟器数字部分和模拟部分完全隔离、可以高精度的输出20mVpp的信号,有效地模拟了激光驾束制导的光场信息,从而为试验研究激光驾束制导武器系统的光信息场的各种特性提供了一个有效的方案。
Through analysis of the principle of laser beam riding guidance, An Analog transmission system of laser beam riding guidance light field based on DSP, FPGA, and high--precision D/A is proposed. The PC sends guidance commands to DSP via RS232 and then processed, the result sent to FPGA which controls DA to generate electrical pulse signal that meets the law of optical information field modulation, the signal of the laser is modulated to thereby obtain a specific field of the op- tical information. The simulator, digital section and analog section completely isolated, can output 20mVpp signal accurate- ly, it simulates light information field effectively and provides an effective trial to study laser beam guided weapons systems.
