| 摘 要： | 针对激光引信易受云烟雾干扰的问题,提出了一种基于脉冲宽度调制技术的激光引信抗干扰方法。计算了不同脉冲宽度条件下的云烟雾后向散射回波功率,并给出了云烟雾后向散射回波功率随发射脉冲宽度的变化规律。分析了不同云烟雾条件下使用不同发射脉冲宽度探测时所得到的回波功率比。实验结果表明,在使用不同脉冲宽度激光探测条件下,云烟雾激光后向散射功率比大于3,使用该方法可有效提升激光引信抗干扰性能。

| Abstract: | In view of the problem that laser fuze is easily interfered by fog and smoke, a new laser fuze anti-interference method based on pulsed width modulation technique was proposed. The fog echo signal power of different pulse width was computed, and the variation of echo signal power under the influence of transmitted pulse duration was given. The echo signal power ratio in different fog and aerosols environment was analyzed by using different pulse width to detect. The experiment results show that by using different pulse width to detect, the ratio of backscattering power is usually more than 3. Therefore, this method can be used to improve anti-interference ability of laser fuze. |
