With a total of 2 patents, his work showcases innovative methods for determining the location of moveable transmitters.
Latest Patents
One of his latest patents is a passive tracking system and method. This system discloses techniques for passively determining the location of a moveable transmitter by utilizing a pair of phase shifts at a receiver. The invention focuses on extracting a direction vector from the receiver to the transmitter. In a preferred embodiment, a phase difference between the transmitter and receiver is extracted using a noncoherent demodulator in the receiver. The receiver is equipped with an antenna array consisting of three antenna elements, which are preferably patch antenna elements spaced apart by one-half wavelength. Three receiver channels are utilized for simultaneously processing the received signal from each of the three antenna elements. Multipath transmission paths for each of the three receiver channels are indexed, allowing for comparisons of the same multipath component across the channels. The phase difference for each received signal is determined by comparing only the magnitudes of received and stored modulation signals to identify a winning modulation symbol.
