Abstract
The receiver through an improved Prony method provides a measure of the frequencies, the angle of arrival (AOA) and the phase of signals at the receiver. The device comprises two antennas spaced a known distance apart. These antennas receive signals at different angles. Signals from the antennas are sent to delay lines. Each delay line experiences a different delay period. Signals are then sent to four correlator circuits whose outputs are analog signals which contain all the information required to solve for the frequencies and the angles of arrival of signals at the receiver. The signals are supplied to a digital processor where a mathematical method is used to solve for the frequencies, the phases and the angles of arrival of signals at the receiver.
