Research on uniform linear array output signal and beamforming

Aiming at the problems of low scanning efficiency and difficult real-time imaging of TKIS-I color helmet mechanical scanning single-beam sonar developed in the laboratory at present, research on high-frequency high-resolution multi-beam imaging sonar is proposed. Multi-beam imaging sonar can be pre-formed into multiple beams using electronic scanning technology, which can simultaneously scan and image a large range, greatly improves the scanning efficiency of sonar. This paper will proceed from the two aspects of the output signal of the transducer array and the principle of beamforming to study some characteristics of the uniform linear array multi-beam sonar, and make a theoretical research basis for the development of high-frequency high-resolution multi-beam imaging sonar.
