Abstract:
1. A method of generating a synthetic aperture sonar (SAS) signal, comprising: moving a sonar array at a first velocity, the sonar array having at least three transmitters and a plurality of receivers, the array having a first length, wherein the first transmitter is positioned at a first fraction of the length along the first length, the second transmitter is positioned at a second fraction of the length along the first length, and the third transmitter is positioned at a third fraction of the length along the first length, and wherein the direction of motion is along a direction from the third transmitter towards the first transmitter; generating a first ping using the first and second transmitter, including: generating a second ping using the first and the third transmitter, including: generating a third ping using the second and the third transmitter, including: wherein a time taken for the sonar array to move between the first and second ping, and between the second and third ping, and between the third and first ping is equal to half the first length divided by the first velocity.
