Hydrography
SeaDarQ has developed an unique application, which uses an unlimited matrix of measuring points for currents, waves and depth measurements. This specific web covers the whole area of interest and supply an accurate hydrographic data for every measuring point.
Sequences of X-band radar images provide information on the movement of wave crests. Analysing the speed, length and direction of these wave crests provides information on the directional spectrum and surface current speeds. The principle of this wave and current analysis of the X-band radar is to measure the movement (speed and direction) of wave crests. In this way, the spatial pattern of individual waves can be determined. From this, a Fourier Analysis obtains the ocean directional wave spectra. The hydrographical component of the SeaDarQ system is therefore capable of deriving quantities of current, water depth and bottom topography from the ocean directional wave spectra in the measurement domain, and can provide spatial information on directional and wave periods 360 degrees around the centre of the radar. This information can be used effectively for Rapid Environmental Assessments.
The Nortek's radar system uses remote sensing by marine radar for measurement of hydrographic parameters to obtain spatial and temporal information on the frequency and directional properties of the wave spectra. This methodology used by SeaDarQ has considerable advantages to in situ numerical modelling and can be used to calibrate and verify wave models.
