New principles of Remote Sensing

We understand the nearby world through our five feelings. Some feelings (touch and taste) need get in touch with of our detecting body parts with the things and that is what our reviews in CRB Tech is all about. However, we acquire much details about our around through the feelings of sight and hearing which do not need close get in touch with between the detecting body parts and the external things. In another word, we are performing Distant Sensing all the time.

Generally, Distant detecting represents the activities of recording/observing/perceiving (sensing) things or activities at far away (remote) places. In remote detecting, the receptors are not in direct get in touch with with the things or activities being noticed. The details needs a physical service provider to travel from the objects/events to the receptors through an all the surrounding medium. The radio waves is normally used as an details service provider in remote detecting. The outcome of an online detecting program is usually an picture comprising the scene being noticed. A further step of picture research and presentation is required in order to extract useful details from the picture. The human visual program is an example of an online detecting program in this general feeling.

In a more limited feeling, remote detecting usually represents the technology of acquiring details about the planet's area (land and ocean) and environment using receptors on board viral (aircraft, balloons) or spaceborne (satellites, space shuttles) systems.

Satellite Distant Sensing

In this CD, you will see many remote detecting pictures around Japan obtained by world statement satellite tv. These remote detecting satellite tv are equipped with receptors looking down to our planet. They are the "eyes in the sky" constantly monitoring our planet as they go round in foreseeable orbits.

Effects of Atmosphere

In satellite tv remote detecting of our planet, the receptors are looking through a layer of environment splitting the receptors from the Earth's area being noticed. Hence, it is essential to understand the consequences of environment on the radio waves traveling from the Earth to the indicator through the weather. The environmental elements cause wave length dependent consumption and spreading of radiation. These results break down the quality of pictures. Some of the environmental results can be fixed before the pictures are exposed to further research and presentation. Thus our reviews of CRB Tech stands for exploring the information
