Simulation of high frequency surface wave radar signal and its scattering from ocean surface

HFSWR is a land-based radar for sensing sea state or oceanographic parameters. The capability of radar can be extended for monitoring other objects such as vessel, low altitude flight, spilled oil, iceberg, tsunami, etc. by enhancement on signal processing. In the research to advance processing algorithm, the data of radar signal on which the computation performance is assessed can be generated by measurement or mathematical model. The empirical data acquired from the measurement campaign contains realistic data but it sometimes includes additional unknown signal elements that probably give additional problems on the assessment process. In other hand, analytical data generated by mathematical model contains only known elements although it lags of realistic conditions. In this research, the analytical data is generated using the existing expression of ocean radar cross-section. The simulation has been developed to construct the radar HF signal based on FMCW and its Doppler characteristics contributed by ocean scattering. The influence of radar frequency and wind are analyzed on the Doppler spectra of received signals. © 2019 IEEE.
