Measurement of sea and ice backscatter reflectivity using an OTH radar system
Abstract
It is essential, during the operation of an OTH-radar system designed for the detection of small targets (aircraft or cruise missiles), that the operators be able to estimate the system sensitivity in real time without targets present. In geographical areas under surveillance that are remote and inaccessible, this technique involves measuring the ratio of the signal returned from the 'ground' to the noise signal. Data from Polar Fox II experimental OTH-radar system was analyzed in order to determine the intrinsic backscatter reflectivity from open ocean, sea ice, and the Greenland ice cap.
