多脉冲激光回波信号处理方法研究

摘要

多脉冲探测体制的激光测距可以有效提高目标探测能力,在这种探测体制下,根据多脉冲激光回波信号的特点,提出了采用平滑滤波与三阶累积量相结合的信号处理方法,并通过仿真,证明了该算法能有效地提高目标探测性能,缩短了探测时间.%The multi-pulsed laser ranging technology is prominent on improving the maximum measuring range. This paper studies on the signal process of the multi-pulsed laser echo, based on the characteristics of the technology, the arithmetic utilizes the pulse cumulation, filter processing and high-order cumulant synthetically, which improves the performance of signal detection and shortens the time for detecting. The detecting performance of the arithmetic is tested by simulation.
