Bistatic HF Scattering from the Sea Surface. II. Experiment

Abstract

Part 2 of the paper presents measurement technique and results of studying the HF radio signals from broadcasting stations reflected from ionosphere and scattered by a rough sea surface. The experiments were carried out during the 7th Ukrainian Antarctic expedition on a board of research vessel “Horizont”. The experimental spectra are compared with the simulated results calculated after the theory of Part 1 of this article. A qualitative agreement between theory and experiment has been found and possible physical reasons for specific features of the signal spectrum are discussed.
