Abstract
A method that includes transmitting coded waveforms simultaneously on multiple elements for several frames, constructing a first multi-input, single output (MISO) system from the codes to model transmit-receive paths, solving system and RF data observation by linear model theory, giving an IR set for the medium, and applying the estimates to a secondary MISO system, constructed by analogy to the first, but with pulses convenient for beamforming in the form of a focused set of single-cycle pulses for ideal focused reconstruction.
