HF Surface Wave Radar - A Review of Activitie
The remote sensing group of the University of Hamburg is working in the field of HF radar since 1980. For the start three CODAR systems have been purchased from NOAA/ERL (developed by D. Barrick’s NOAA group). Based on 16 years of experience a new system called WEllen RAdar (WERA) has been designed at the University of Hamburg in 1996. The new design aims to be as flexible as possible in order ...
متن کاملHistory, Present Status, and Fu HF Surface-Wave Radar
HF surface-wave radars (HFSWRs) offer two distinct advantages when used over the sea: with vertical polarization, they see beyond the horizon, and the interaction of their signals with ocean waves is simple and well understood. As a result, many HFSWR research test programs were conducted in the U.S., beginning 35 years ago. This author was fortunate to have been immersed in these programs from...
متن کاملWave Height Estimation from Shipborne X-Band Nautical Radar Images
A shadowing-analysis-based algorithm is modified to estimate significant wave height from shipborne X-band nautical radar images. Shadowed areas are first extracted from the image through edge detection. Smith’s function fit is then applied to illumination ratios to derive the root mean square (RMS) surface slope. From the RMS surface slope and the mean wave period, the significant wave height ...
متن کاملHF Surface Wave Ra in Adverse Con
For the past 12 years the Canadian Department of National Defence and Raytheon Canada Limited have collaborated on a cost-shared programme to develop an Integrated Maritime Surveillance (IMS) system based on HF Surface Wave Radar (HFSWR). The primary objective behind the programme was to demonstrate the capability of HFSWR to continuously detect and track surface targets (ships and icebergs) as...
متن کاملTarget Classification, Recognition and Identification with HF Radar
Radars operating in the HF band achieve extremely long range detection by exploiting propagation modes which preclude many of the standard target classification techniques, at least in their conventional form. Yet, in order to take full advantage of an over-the-horizon detection capability, reliable target classification, recognition and identification is essential. This paper explores the opti...
