Abstract

—The passive time-reversal beamformer is a 1 ports device with orthogonal channels. Beamforming is achieved using simultaneous time reversal focusing on the output ports with the only input waveform. Utilizing this method, an antenna array can be supplied with focused signals of controlled complex weights and achieve beam steering. A precorrection method is developed in this letter to normalize the weights of the output signals at the focusing time, avoiding a long optimization step of beamformer designing. The theory is developed in this letter, followed by experimental validation.
