Measurement of the condition of the sea by ionospheric backscatter radar
Abstract
The principles of meteo-oceanic parameter measurements are introduced, and the HF sky-wave radar equipment at Valensole is described. The maximum range of the radar, which depends on the reflector-layer altitude and on the frequency used, varies between 2500 and 4000 km. Consideration is given to the question of how to recognize the noise signal that is received and how to extract from it the information concerning the sea surface. The solution involves not only the detection of the echo amplitude but also a comparison of the phase of the received signal with that of the emitted signal. Results are presented which show that wind-directions measured by the radar are in good agreement with meteorological maps.
