Abstract

The invention relates to a multi-beam profile sonar signal processing device, characterized in comprising a host computer above water, an emission and control DSP part disposed on the underwater robot, an emission signal conditioning part, a power amplifier, an emission transducer, a, an analog signal acquisition transmitting part, a data receiving port and a DSP parallel signal processing part. The emission and control DSP part connected with the water host computer by cable receives command of water host computer, the emission signal conditioning part amplifies, filters and isolates the analog signal produced by the emission and control DSP part, and then amplified by the power amplifier, the emission transducer emits the signal underwater after electrical / mechanical conversion; the reception transducer receives the echo which is converted to digital signal by the analog signal acquisition transmitting part after performing mechanical / electrical conversion, and transmitted to the data reception port, then transmitted to the water host computer by cable after processing by the DSP parallel signal processing part. The invention can be applied widely in the process of detecting azimuth of undersea oil pipeline.

Description

technical field [0001] The invention relates to a multi-beam profile sonar signal processing device using a high-speed DSP (digital signal processor). Background technique [0002] In recent years, with the development of sonar technology, higher and higher requirements have been put forward for the large-capacity real-time signal processing capability of the sonar signal processing system. Most traditional active sonar signal processing systems use dedicated hardware structures to complete specific data processing tasks. The back end of the transducer is directly connected to data conversion and acquisition, and the data enters the digital signal processor for processing after analog-to-digital conversion. This type of system can only target fixed transducers and has a fixed processing speed. Once the transducer changes or the processing speed is higher, the system will be powerless. Traditional profile sonars are mostly single-beam, low-frequency, and high-power shallow s...
