EARTH REMOTE SENSING

Earth Remote Sensing is a technique using satellites or planes to collect earth reflection signals and use the signal for analysis.

TOPOGRAPHIC CORRECTION METHODS FOR LANDSAT IMAGES

Topography has a strong impact on earth remote sensing. The inclination of the earth's surface and vegetation will both affect the irradiance and the bidirectional reflectance distribution function (BRDF). There are several other methods being developed by other researchers. This paper has reviewed and tested some of the commonly used methods.

IONOSPHERIC SIGNAL DELAY CORRECTION FOR NASA SNOOPI PROJECT

Any signal penetrating through the earth's atmosphere will experience delay caused by the earth's ionosphere. GPS uses Klobuchar's method for the correction and Galileo uses NeQuick G model for the correction. I am applying both methods to the NASA SNOOPI project and comparing the two methods.

SOIL MOISTURE SENSING USING SIGNAL OF OPPORTUNITY

Using the existing broadcasting satellite signal, we are able to capture the directed and reflected signal from the ground. The reflected signal from the earth's surface will have some property change. By comparing the directed and reflected signal, information about the surface such as soil moisture can be retrieved.
