A joint inversion device of sea surface wind field and sea waves

Abstract

The invention discloses a joint inversion device of sea surface wind field and sea waves, wherein the device includes: a calibrating module for performing radiometric calibration on a synthetic aperture radar image in a wind field database; a splitting module for splitting the filtered image into a plurality of subsidiary images according to preset size; an interpolation calculating module for obtaining external wind direction information by a man-machine interactive method, and obtaining wind directions of corresponding the subsidiary images; an inversion module for performing inversion to obtain a sea surface wind field; a separation processing module for inputting the sea surface wind field, separating by a wave number separating method to obtain an image spectrum of the sea waves and an image spectrum of surge of the synthetic aperture radar image; and a joint inverting module for performing joint inversion on the obtained spectrum of sea wave to obtain sea wave elements. The joint inversion device of sea surface wind field and sea waves achieves the purpose of avoiding repeating input operations of external information, can accurately and efficiently feed back the synthetic aperture radar (SAR) sea surface wind field, guarantees that the wind filed and the sea waves have the same spatial resolution, and improves accuracy of an inversion result.

Description

technical field [0001] The invention relates to the technical field of synthetic aperture radar, in particular to a device for processing joint inversion of sea surface wind field and sea wave. Background technique [0002] With the development of marine resources and frequent maritime activities, such as the development of marine transportation and sea fishing, the attention of marine accidents has also increased. Maritime accidents will bring huge disasters to the coastal countries of the world politically, economically and militarily. They will not only cause casualties and property losses, but also bring adverse effects on social development. Maritime search and rescue work is also increasingly favored by coastal countries. Therefore, it is indispensable information for people to carry out marine sports to obtain the wind field and wave conditions on the sea surface. [0003] However, the traditional observation methods of sea surface wind field and sea waves are mainly...
