Abstract:
Direct GPS signals are used for navigation and positioning purposes by a diverse set of users. However, this project describes a method for utilizing reflected Global Positioning System (GPS) signals to form an image of targets within a region of interest. The principle is based upon a type of bi-static synthetic aperture radar (SAR) in which a matched filter technique is employed to perform the image reconstruction by the correlation of direct and reflected GPS signals. This method relies upon the fact that each component of the received signal resulting from a reflection of an individual target is subjected to a unique chirp. A major challenge was the appalling signal to noise ratio associated with the received reflected GPS signals. The reconstruction method resulted in an undesirable point spread function (PSF) which seriously smears the reconstructed.
