A new application using reflected Global Positioning System (GPS) signals collected by a tightly integrated GPS receiver for ground object detection and soil moisture estimation is developed. Several operational considerations are discussed to successfully acquire and track the weakly reflected GPS signals from the ground surface. Both right-hand circular polarization (RHCP) and left-hand circular polarization (LHCP) antennas are employed so that the direct and reflected signals can be received… CONTINUE READING
