Description

technical field [0001] The invention relates to the technical field of marine acoustic equipment, in particular, to a ZYNQ-based forward-looking sonar signal processing hardware system. Background technique [0002] Due to the complexity of the underwater environment in the ocean, sound waves that can transmit long-distance in the water have become an effective information transmission method in the process of ocean exploration and research. Although the lower the frequency of the acoustic signal, the less the energy is attenuated underwater, but in order to ensure the resolution of the image, the general imaging sonar system still selects a higher frequency signal. Sonar imaging technology uses acoustic signals as the carrier of information, and generates and displays images through imaging equipment for the identification, positioning and display of targets or obstacles. Common forward-looking sonars are divided into single-beam imaging sonar, multi-beam imaging sonar and...
