Abstract
Systems and methods for tracking a remote source and monitoring and controlling the angular orientation of an antenna array, including a first antenna portion and a second antenna portion, are provided, including a sum-difference structure coupled to a first output of the first antenna portion and a second output of the second antenna portion, where the sum-difference structure provides both a sum power signal and a difference power signal, and where both the sum power signal and the difference power signal have associated RSSI values generated by an RSSI circuit. Systems and methods provided herein further include a sum-delta processor configured to utilize the RSSI values to generate an off-bore-sight angle of the antenna array relative to a position of a transmitting radiofrequency signal source.
