通过分析国内外关于机载激光测深系统中传统的MONTECARLO模拟方法所存在的缺点和弊端 ,提出一个新的研究思路 ,该方法思路简单 ,可扩展性强。通过修改几个关键参数 ,可以比较客观的得出在这种情况下的回波波形形状。通过模拟 ,认为在单次散射率ω0 大的海域 (或季节 )或一定角度入射海面的情况下 ,有例于海底信号的突出。 By analyzing the shortcomings and shortcomings of traditional MONTECARLO simulation methods in airborne laser sounding system at home and abroad, a new research idea is proposed. The method is simple and scalable. By modifying a few key parameters, the shape of the echo waveform in this case can be objectively derived. Through simulation, it is considered that in the case of a sea area (or season) having a large single scattering rate ω0 or a certain angle of incidence on the sea surface, there is an example of a prominent signal at the seafloor.
