Multi-beam sonar multi-channel seabed echo and movement attitude and position simulator

Abstract

The invention discloses a multi-beam sonar multi-channel seabed echo and movement attitude and position simulator which comprises a data generating module, a control module, a data storage module, a digital-to-analog conversion module and multi-channel seabed echo signals. Multi-beam seabed data can be generated by the data generating module, the control module is connected with the data generating module, the data storage module and the digital-to-analog conversion module are respectively connected with the control module, and the multi-channel seabed echo signals are connected with the digital-to-analog conversion module; a control interface and synchronous signals on the control module are respectively connected with tested multi-beam sonar, and the multi-channel seabed echo signals can be outputted; movement attitude and movement position data can be generated by the data generating module in real time after the synchronous signals are received, and can be outputted to to-be-tested equipment via an output interface, and pulse-per-second signals are simultaneously outputted from a pulse-per-second signal interface on the control module. The multi-beam sonar multi-channel seabed echo and movement attitude and position simulator has the advantages that real measurement procedures can be simulated in laboratories, and accordingly problems of high cost and long cycle of debugging and testing modes due to the fact that multi-beam sonar devices and auxiliary equipment need to be transmitted to specific sea areas to be actually measured can be solved.

Description

technical field [0001] The invention relates to a signal simulator, in particular to a simulator for generating multi-beam sonar multi-channel seabed echoes and motion attitude and position. Background technique [0002] Multi-beam sonar equipment plays an extremely important role in detecting seabed topography, constructing marine engineering, developing marine resources, developing marine science, and safeguarding marine rights and interests. [0003] Existing multi-beam sonar equipment mainly includes: multi-beam bathymetric sonar device, multi-beam side-scan sonar device, multi-beam shallow stratum profiler, etc., among them, multi-beam sonar device controls signal source and transmitter, through The transmitting transducer array radiates the acoustic signal to the water body, and the acoustic signal scattered by the detection target is received by the receiving transducer array, converted into a digital signal after conditioning by the signal receiver, and after a serie...
