【摘要】 对激光测距中出现的新的干扰问题进行了研究。分析了干扰现象,确定了干扰产生的原因,提出了消除干扰的方案,解决了存在的干扰问题。新出现的干扰距离是原大气近程散射干扰距离的2.5倍,是由于大气污染严重造成的,采取了时控增益延长法,将近程抑制距离增加2.5倍,较好地解决了干扰问题,且不影响近目标测距。通过试验证明,大气污染造成近程散射干扰增加的观点的正确,采用延长时控增益的方法抑制新的近程干扰是可行的。更多还原

【Abstract】 The new interfere of laser distance finding was studied in the paper. Analyzed interferential electrophoresis, confirmed the reason of bringing interfere, presented a precept of removing interfere, and resolved interferential questions. The new interferential distance is longer than the originally short dispersion of atmosphere for three times, which was produced by bad pollution of atmosphere. Distance restraining short interferes increased three times with extended method for gain of time controlling. The method removed interfere questions, which didn’t affect distance finding for near aim. The following result was proved based on the test: interferes of short dispersion increased because of bad pollution of atmosphere; the new disturbance of short dispersion was well restrained by extending gain of time controlling.更多还原
