Estimation of sea-wind parameters using a Doppler navigation system

Abstract

We propose the procedure for measuring the parameters of the sea-surface wind using a Doppler navigation system (DNS) fixed on an aircraft. The DNS with an antenna with x- and y-configured beams is considered. It is shown that the use of data from the y-configured beam model is not enough to provide the required accuracy in determining the speed and direction of the wind. In this regard, an algorithm is proposed for a two-stage measurement of the parameters of the sea-surface wind. The applicability of the proposed approach is confirmed by the results of mathematical modeling, the errors in estimating the speed and direction of the wind are given.
