中波红外激光器干扰效果对比实验研究

Comparative experimental study on interference effect of medium wave infrared laser

使用两种不同频率(1 kHz与15 kHz)的中波红外激光器对同一目标进行了远距离(15 km)干扰效果对比实验,分析了激光器频率与干扰效果的关系,计算了到达探测器的激光功率密度。实验结果表明:在激光器波长、平均功率一致的情况下,高重复频率(15 kHz)中波激光器的干扰效果要明显优于低重复频率(1 kHz)的中波激光器,实验结果对光电对抗装备的研制具有一定的指导意义。

Two different frequencies(1 kHz and 15 kHz)of medium-wave infrared lasers were used to compare the interference effect at a distance(15 km)to the same target,the relationship between laser frequency and interference effect was analyzed,and the laser power density reaching the detector was calculated.The experimental results show that the interference effect of the medium-wave laser with high repetition frequency(15 kHz)is obviously better than that of the medium-wave laser with low repetition frequency(1 kHz)when the laser wavelength and average power are the same.The experimental results have certain guiding significance for the development of photoelectric countermeasure equipment.
