A full paper has been published in the conference
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 to allow easy
adjustment to different requirements, i.e. working frequency,
spatial resolution, and antenna configurations.
The first part of this paper
describes the technical solutions available to achieve
resolution in range and azimuth. Modulation techniques for range resolution
like Pulses and Frequency Modulation (FMCW) are compared, as well as
Direction Finding and Beam Forming for azimuthal resolution. A short
introduction to the algorithms is given.
The second part discusses the hardware and software components which
form a WERA and are now commercially available.
The third part shows an example of a monitoring system bringing together
HF radar remote sensed data and numerical models.
