摘要 为了满足激光侦察的快速反应需要,应尽可能地缩短从激光入射到波长显示的时间间隔.在保证频谱分辨率不变的情况下,通过减少参与FFT运算的点数来缩短运算时间,提高激光波长测量装置的反应速度.分析了这种改进算法的原理,并给出了实验结果.实验结果表明在本系统中此方法切实可行. To satisfy the desire of quick responses to the laser signal in the reconnaissance, it is necessary to shorten the latency from the incidence of the laser to the display of the laser wavelength on an instrument as much as possible. Under the condition of unchanging the spectrum resolution, the latency of the laser wavelength measurement system is improved by reducing the samples of FFT operation. The principle of the algorithm is presented and the results are given. The experiment results indicate that the algorithm is practical in the system.
