Abstract

The invention provides a data processing method of a synthetic aperture radar ocean wind-field retrieval variation model. Aiming at the problem that the EnVar and MCVar variation model process is high in the operand and is time consuming in the prior art, by means of taylor expansion and linearization cost function and based on Armijo inexact line search technique, the data processing method of a synthetic aperture radar ocean wind-field retrieval variation model can realize a rapid solution of using iteration to solve minimum of the cost function, thus improving the operation time efficiency.

Description

technical field

[0001] The invention relates to the field of information technology, in particular to a data processing method for inverting a variational model of a sea surface wind field by a synthetic aperture radar. Background technique

[0002] Sea surface wind field data play a very important role in meteorological forecasts, ocean wave forecasts, long-term changes in atmospheric and ocean current systems, and the development and application of marine resources; A hot issue. In the prior art, the method of inverting the sea surface wind field by synthetic aperture radar is generally used, and its advantages are mainly reflected in the following aspects:

[0003] (1) High spatial resolution: Modern high-tech warfare puts forward higher requirements for refined sea surface wind field. The spatial resolution of synthetic aperture radar is tens of meters or even several meters, which is much higher than that of scatterometer and radiometer, so it is more suitable for Nea...
