| 摘 要： | 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。

| Abstract: | The algorithms are presented which have been developed for r esearching the relation between the formation of returned waveform and environme nt parameters in Laser Airborne Sounding Lider. These algorithms have been impr o ved than those noted in some references, and the efficiency of calculation is re markably improved, by this mathematical model, the authors noted large ω0 or a definite scan angle is helpful to detecting the bottom returns. |
