Abstract
It is well known that the reflection characteristics of object with rough surface in optical sense like the paddy field vary with the view angle, the solar angle and their growth level. This is the reason why it is difficult to exactly analyze the agricultural data obtained by the space-borne and the air-borne sensor MSS. It will be very convenient and helpful for observing some ground truth or correcting the MSS data if there is such a simple model as can simulate accurately and easily the reflection characteristics of object with rough surface.
In this paper, we describe a new and powerful reflection model for object with rough surface like the paddy field. This model is named “Equivalent Reflectance Model”.
This model can permit us good and reasonable explanation of the view angle characteristics temporal ones and things like that the ground truth or MSS data contain in themselves.
It can also give us the precise equivalent reflectance of the paddy field on any conditions.
