Abstract
The aim of this work is to develop an acoustical imaging system which permits high speed data acquisition with simple hardware. In the previous works [1,2], we have introduced the holographic sonar using transmitting pulses modulated by the system of orthogonal functions. The imaging system transmits uncorrelated pulses from multiple transmitters simultaneously, and detects the echo wave-front by the array of receivers. With the recorded waveforms of echo, beam-forming is accomplished indirectly.
