80年代后期,加拿大、澳大利亚、意大利和美国等国,相继研制成机载激光海深勘测系统。这项研究的目的,是设计一种能在各种环境下由飞机测绘浅海和海岸深度图的新型系统。该系统与传统的舰船海深声波勘测系统相比,具有速度快、价格低等明显优点。据认为,机载激光海深勘测系统对各国有效地了解海情,执行近海防御和开展广泛的商务航海活动都有十分重要的意义。优缺点机载海深勘测系统的主耍优点是勘测速度极快。据美海军海洋局测算,此系统如果每年 In the late 1980s, Canada, Australia, Italy and the United States and other countries, have been developed into airborne laser sea depth survey system. The aim of this study was to devise a new system that could map shallow depths and coastal depth maps by airplanes in a variety of environments. Compared with the traditional ship-sea deep sound wave survey system, this system has the obvious advantages of fast speed and low price. It is considered that the airborne laser sea-depth survey system is of great significance to countries in effectively understanding the maritime situation, implementing coastal defense and conducting a wide range of business navigation activities. Advantages and Disadvantages Airborne sea depth survey system has the main advantage of extremely fast survey. According to the United States Naval Oceanic Administration estimates that if this system every year
