Abstract

The invention discloses a multi-sensor data sharing method in a cluster environment. The method comprises the steps that (1) system working parameters are set; (2) acquisition time of a single piece of original sonar echo data is calculated, the number of maximum sensor data in a corresponding time period is determined, and initial storage space is distributed; (3) data uploaded by all sensor nodes is received and stored; (4) when collection of a single piece of sonar data is completed, current sensor data is ordered according to collection time, then the sensor data in the corresponding time period of the currently collected sonar data is intercepted, and data packing operation is performed; (5) sending times are calculated, and the sensor data is sent to a subsequence data receiving thread according to a fixed size and the sending times; and (6) the data receiving thread completes data receiving, performs unpacking and then performs subsequent signal processing. According to the data sharing method, the sensor data can be easily shared between different threads, expansion is easy, and limitation of the type and number of the sensor data is avoided.

Description

technical field [0001] The invention belongs to the field of data sharing, in particular to a synthetic aperture sonar multi-sensor data sharing method in a cluster environment. Background technique [0002] Synthetic Aperture Sonar (SAS) is a high-resolution imaging sonar, which has the advantage that its imaging resolution is independent of its operating frequency and imaging distance, and can be widely used in underwater archeology, seabed oil exploration and searching for underwater lost objects, etc. . In order to carry out high-precision imaging, it is necessary to compensate various errors caused by the motion of the carrier, and convert the multi-subarray signals received in the non-ideal motion state into signals in the ideal motion state, and then perform imaging processing. In the process of synthetic aperture sonar signal processing in a cluster environment, the first thing involved in motion compensation is the sharing method of multiple sensor data. Since the...
