An emerging area in microwave remote sensing is to use global navigation satellite service (GNSS) signals, like GPS, to form a bi-static radar by deploying a receive-only (i.e. passive) instrument to measure signals reflected from the Earth's surface. It is possible, and has been demonstrated using XM Satellite radio, to use other existing space borne transmitters. To this end, we propose to demonstrate the use of these so-called signals-of-opportunity (SOP) to perform bi-static active microwave remote sensing of land surfaces. Specially, we will demonstrate the exploitation of geostationary satellite transmissions within the direct broadcast service (DBS) to sense changes in a reflecting surface (e.g., the ground). While past research within the community has focused on using reflected GPS signals to sense ocean winds and soil moisture, there is a paucity of investigation using higher frequencies. We see potential in using multiple satellite downlink frequencies to sense surface prope...
