Abstract - -
Surface currents normally are difficult to measure. Only a set of Lagrangian
drifters observed from fixed stations or from an aircraft or by satellite can
give adequate information. Beneath this there is a new and powerfull field
measuring tool which functions with a decametre backscatter radiowave RADAR.
Two (or more) such fixed RADAR stations on land or on island can remotely
measure the surface currents in front of them with high resolution in space and
This paper has two aims: first, to give a short explanation of the physical
principles of the backscatter RADAR and to show its requirements and its
limits, and secondly, to demonstrate the possibilities offerd by this RADAR
with an example of the coastal surface current off Norway.
