Time Modulated Array for dual function radar and communication

A Time Modulated Array based technique is used to simultaneously do a radar function in the main lobe and a communication function in the side lobes. It uses an averaging to do the radar function, while the communication is done with the variation from an intermediary pattern to another. A 12-antenna array is shown with a stable main lobe for radar application and a variation of the magnitude of the side lobes to perform an Amplitude Modulation at 55° from the main lobe.
