Problems solved by technology
[0005] However, in the process of obtaining data products, the data quality may be abnormal, and the reasons for the abnormal data quality mainly include: (1) The load of the microwave scatterometer is abnormal; (2) Data receiving, preprocessing and processing Abnormalities in the process; (3) Anomalies caused by auxiliary data not being in place in time; (4) Abnormalities caused by extreme weather such as rainfall, snowfall, and hail
If these abnormal data are not eliminated or marked, wrong conclusions will be drawn, and ultimately, the use effect of the data will be affected
At present, the microwave scatterometer business system lacks reliable quantity and quality detection technology, and the abnormal data is mostly determined by the watchman observing the wind field distribution map or the backscatter coefficient distribution map, which requires a high working experience of the watchman , the accuracy of data quality detection cannot be guaranteed, and the detection efficiency of data quality is extremely low

The data quality detection method provided by the embodiment of the invention comprises the following steps: obtaining a wind vector data set obtained by monorail detection of a marine dynamic environment detection satellite; obtaining M sub-data sets from the wind vector data set, M being an integer greater than 0; and analyzing each sub-data set in the M sub-data sets to obtain a data detection result of the wind vector data set. According to the data quality detection method and device and the electronic equipment provided by the embodiment of the invention, the accuracy of data quality detection can be improved, and meanwhile, the efficiency of data quality detection is also improved.
Description
technical field [0001] The present application relates to the technical field of marine remote sensing surveying and mapping, in particular, to a data quality detection method, device and electronic equipment. Background technique [0002] The sea surface wind field is an active factor that affects waves, currents, and water masses, and is a basic parameter of ocean dynamics. The monitoring of the global ocean wind field is crucial for disaster prevention and mitigation in coastal areas, protection of the marine environment, and promotion of marine-related scientific research. It is of great significance, and the microwave scatterometer has become the most important means of observation of the global sea surface wind field due to its characteristics of all-day, all-weather, high temporal and spatial resolution, and large coverage. [0003] The microwave scatterometer is a calibrated radar, which is used to actively transmit electromagnetic waves to the sea surface and receiv...
