As in conventional phased-array radar, we assume a uniform linear array of M PWAS, with each PWAS acting as a pointwise omnidirectional transmitter and receiver. The PWAS in the array are spaced at the distance d, which is assumed to be much smaller than the distance r to a generic, far...
(EUSR) will be presented. The transmitter beamforming, receiver beamforming, and phased array pulse-echo concepts will be developed fromfirst principles. The practical implementation of the EUSR algorithm, and experimental validation and calibration of this method will be presented. The chapter will...
