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...
In this paper, a 3-D electromagnetic inverse scattering algorithm based on analytical singular value decomposition (SVD) of the scattering integral operator is proposed. The spectral expansion of the dyadic Green's function is employed to derive continuous SVD of scattering integral operator. The analytical formulation of singular values and vectors is straightforward without considerable computation...
Multiple target tracking in over-the-horizon radar (OTHR) suffers from two major challenges due to the multipath propagation phenomenon. The first is multipath detection that detects appearing and disappearing targets automatically, while one target may produce s tracks for s propagation paths. The second is multipath tracking that calculates the target-to-measurement-to-path assignment matrices to...
