    Kongsberg Seatex RADius Technical description, rev 0 TECHNICAL DESCRIPTION The product RADius (patent pending) represents a completely new way of utilising radar principles in short range and direction monitoring. RADius is mainly meant to be used in operations where increased safety is crucial. The system could typically be used to control or assist automatic dynamic positioning (DP) of a vessel.

  • Page 16: Design Principles

    Kongsberg Seatex RADius Technical description, rev 0 Innovative technology The implementation is fully solid state and based on measuring reflected signals from a number of transponders who represent targets in the nearby area. Each reflected signal is mixed with a unique ID in order to separate different transponders from each other. Advanced signal processing allows simultaneous and continuous measurements from up to five transponders.

    Kongsberg Seatex RADius Technical description, rev 0 3.2.1 Distance and bearing determination Transponder #1 Transponder #3 bearing Transponder #2 Interrogator Figure 3 Relative distance and bearing The RADius Interrogator measures distance and bearing to the transponders. It can operate on one transponder alone or up to five simultaneously.

    Kongsberg Seatex RADius Technical description, rev 0 RADius measures range based on the FM-CW radar principles. It sweeps the frequency transmitted and mixes the transmitted signal with the received signal. The transmitted signal has changed frequency during the flight time of the received signal and it is the difference between the transmitted frequency and the received frequency that is measured.
