A Forward Scatter Radar (FSR) system is clutter-limited, rather than noise limited. It does not have range resolution so the clutter is collected from the whole surface illuminated by the antenna radar. This paper introduces an approach to generate a signal with the same spectral and statistical properties of sea clutter at very low grazing angles. We proceed with a practical approach based on the...
High-frequency (HF) ocean radar systems have demonstrated their capability to capture the signal from tsunami currents after the 2011 Tohoku earthquake and tsunami. However, these systems were configured for mapping surface currents in the coastal zones and not for detecting specific patterns of tsunami waves in real-time. The WERA® ocean radar system was optimized for tsunami alerting and installed...
Interferometric sonar systems apply the phase content of the sonar signal to measure the angle of a wave front returned from the seafloor or from a target. It collect a big data - datasets that are so large or complex that traditional data processing application software is inadequate to deal with them. The recording a large number of data is associated with the difficulty of their efficient use....
