A new type of harbour surveillance radar with diversity processing

This paper introduces the harbour surveillance radar HSR-1128 developed by Nanjing Research Institute of Electronics Technology. The radar has been operating in Tanggu Harbour VTS Center in Tianjin for more than one year. This X-band radar utilizes frequency diversity, polarization diversity and time diversity to significantly suppress sea clutter, rain or snow clutter and radar interference. The system performance and operating principles of this radar are described; the advanced techniques it uses and the operating status are also stated.
