激光雷达的双门限检测技术研究

文章提出了一种既适用于微弱目标检测,又能快速检测出强目标的双门限检测方法。 该方法对于强信号捕获时间较短,提高了激光雷达快速捕获目标的能力;对于弱目标,通过大量的相关处理,可实时地检测到,提高了激光雷达对微弱目标的检测能力。外场实验结果表明:该方法可有效地提高激光雷达的测距能力,迎头截获距离可提高约2～3倍。

The Study of Double Threshold Detection Method in a Laser Radar

A novel method of double threshold detection is presented.The method is not only suitable for detection of small target,but also fast to detect strong target.For a strong echo target,the capture time is shorter,the method improves the speed of the laser radar's capturing target.While for the weak target,with many correlation processing,the target can be detected on real time,this method improves the laser radar's detection ability for small target.External experimental results show that the method can improve the detection distance of the laser radar,and the head-on intercept capture distance can improve about 2~3 times.
