卫星遥感水下地形地貌的模糊判别模型
（1） 卫星传感器所接收到的海水信号模型：
式中，
为天空光辐射及水面对天空漫射的反射；
，为离开水表面的向上辐射，即水介质的散射辐射，
为水表面的太阳辐照度，n为海水折射率，
为大气传输率，
为海底底质反射率，
为海水衰减系数，
为传感器垂直方向的视角；
为太阳角，z为遥感水深值；
为大气柱上的大气分子及悬浮微粒的散射辐射；
为水面的反射辐射，E为大气顶部的太阳辐照度，
为海面反射函数。

The Great Artesian Basin, also known as the "Great Australian Basin", is the world's third largest basin and the world's largest gravity basin. In Australia, is the world's largest gravity basin, located in the eastern part of the Australian mainland. In the Australian rock layer, covered with impermeable layer, the eastern part of the rain, the formation of water, groundwater flow at an annual rate of 11 to 16 meters flowing to the western region. Confined water through the drilling or natural springs and other gushing surface, so the river basin hence the name. The development of animal husbandry in Australia benefited from this unique terrain.
Satellite positioning system that global positioning system (Global Positioning System), is the use of satellite to accurately locate the technology. Can guarantee at any time, any point on the earth can also observe four satellites in order to achieve navigation, positioning, timing and other functions. Can be used to guide aircraft, ships, vehicles, and individuals, safe and accurate along the selected route, arrived at the destination on time, but also can be applied to mobile phones and other pursuit.
