Abstract

The equipment is for transmission of manoeuvring data from one ship to another where both are provided with navigational radar, and the first vessel is located within the radar sweep of the second. On the first vessel is a transponder which provides a response signal dependent upon the receipt of a radar signal pulse from the radar of the second ship. Also on the first ship is an encoder for the response signal in agreement with the type of current or forthcoming manoeuvre of the first vessel. The transponder, comprises a transmitter for sending a signal with the same carrier wave frequency as that of the received radar signal pulse. It also incorporates a frequency meter for the carrier wave frequency of the received signal pulse, and a comparator for the signal corresp. to the measured signal and that corresp. to the transmitter carrier wave frequency. A further device adjusts the transmitter carrier wave frequency to that of the carrier wave. (Provisional Basic advised week 83/46).
