Abstract

The invention discloses an interferometric synthetic aperture sonar signal processing system based on a blade server. The system comprises a blade center, and a data receiving and storage unit of theblade center performs block processing on received original echo data to obtain a plurality of data blocks which are allocated to imaging units respectively; processing threads running in the imagingunits perform synthetic aperture imaging on the original echo data in the data blocks in a parallel mode to obtain synthetic aperture sonar images; elevation reconstruction units receive the syntheticaperture sonar images generated by the two imaging units respectively and calculate elevation information of an imaging area; the data receiving and storage unit, the imaging units and the elevationreconstruction units are implemented on the basis of the blade server, the units are linked to one another through a high-speed network for data transmission, and a dual-assembly-line type structure is formed to realize multi-thread parallel processing of double-sided sonar signals. The system is high in signal processing capability and integration degree, and the requirements of a loading ship for the InSAS (interferometric synthetic aperture sonar) real-time signal processing system can be met.

Description

technical field [0001] The invention belongs to the technical field of interference synthetic aperture sonar signal processing, and more particularly relates to a blade server-based interference synthetic aperture sonar signal processing system and method. Background technique [0002] Synthetic aperture sonar (SAS) is an underwater two-dimensional imaging technology that can obtain high azimuth resolution independent of range. Interferometric Synthetic Aperture Sonar (InSAS) is based on Synthetic Aperture Sonar (SAS) and adds one (or more) receiving arrays in the vertical track direction, and obtains the height information of the scene by comparing the height of the phase, so that Get a 3D image of the scene. Interferometric synthetic aperture sonar (InSAS), as a three-dimensional high-resolution imaging sonar, has the advantages that the resolution of synthetic aperture sonar is independent of imaging distance and operating frequency, and the advantages of high precision ...
