摘要
针对脉冲激光雷达易受自然环境干扰的问题,提出了采用小波分析的抗干扰方法,通过脉冲激光对真实目标和干扰目标的回波差异分析,采用小波分析对激光雷达回波进行处理。在此基础上建立脉冲激光雷达回波的数学模型,设计基于小波分析的抗干扰算法,通过仿真验证,该方法具有良好的抗云、雾、烟尘等自然环境干扰的性能。
Aiming at the vulnerability of pulse laser radar to the interference of natural environment,this paper proposes an anti-interference method based on wavelet analysis.Firstly,the echo differences between the real target and the interference one were analyzed through pulse laser,and then the laser radar echo was processed by using wavelet analysis method.Thirdly,on the basis of the analysis,the mathematical model of pulse laser radar echo was built and the anti-interference algorithm was designed.The simulation results verify that this method can resist natural interferences such as cloud,fog,and smog effectively.
