UHF radar system tested on the Bridge of Yangtze River

This paper presents a field test of UHF radar system on the Bridge of Yangtze River in China. Recently a set of UHF radar system has been developed for vessel surveillance and estimation of surface velocity profile across the river. The radar operates at 300MHz to match the dimension of water wavelengths. Another aim of ship surveillance is to protect the pier against ship collision. The transmit power of the radar is under 5W and the maximum range is 2km. This paper gives the design methods and waveform parameters of the system, some results of field test are also presented.
