WebHigh-frequency waves (3-30 MHz) interact with the sea surface. Thus, a high-frequency surface wave radar (HFSWR) is well suited to perform remote sensing of the sea. The HFSWR coverage range is not limited by the radio horizon: it is possible to keep watch over the sea up to a few hundred kilometers from the coastline. WebFrequency Vs. λ. when wavelength is high, frequency is low and vice versa. In experiment 3, as the frequency increases, the wavelength decreases.
