The invention relates to a VTS (
Virtual Terminal Service)
system based on distributed radars. The VTS
system comprises an
information transmission subsystem, as well as a plurality of distributed
radar subsystems, a VHF (
Very High Frequency) communication subsystem, an AIS (
Automatic Identification System) subsystem, an environment subsystem and a comprehensive
information processing and display subsystem in communication connection with the
information transmission subsystem respectively; each distributed
radar subsystem acquires, records and stores dynamic information of a waterway ship, and transmits the dynamic information to the comprehensive
information processing and display subsystem via the
information transmission subsystem; each distributed
radar subsystem specifically comprises a
cascade transmission module in communication connection with the information transmission subsystem, a plurality of short-range radars in communication connection with the
cascade transmission module respectively, and a long-range radar in communication connection with the
cascade transmission module. The VTS
system meets the requirements of inland waterways having complex environment and high dynamic target resolution requirement for no blind area detection, can well adapt to management and
navigational aid services of inland waterways, and ensures the integrity and the consistency.
