Description

technical field [0001] The present 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 complex underwater environment in the ocean, sound waves that can be transmitted over long distances in water have become an effective way of information transmission in the process of ocean exploration and research. Although the lower the frequency of the acoustic signal, the less the energy will attenuate 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 a carrier to transmit 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 imag...
