RADAR STATION FOR SHIP NAVIGATION Russian patent published in 2012 - IPC G01S7/00 

FIELD: physics.

SUBSTANCE: in the method of generating composite phase-shift keyed signals for a ship radar station, each signal segment includes a pulse signal strobe in the middle of the signal segment, and the duration of the pulsed signal strobe is equal to the maximum delay of the signal reflected from a far away object for which the scale of the radar station is intended. The non-periodic composite signal is presented in form of time-concentrated packets whose recurrence interval is equal to the maximum delay to the target, and the time-concentrated packets are arranged such that signals reflected from near and far targets do not cross in time. In the ship radar station using composite phase-shift keyed signals, the signal generating and processing device is part of an antenna post and lies not more than 1 m from the radio transmitter. The signal generating and processing device is based on a programmable logic device (PLD). The PLD is connected to a processor for processing and computing navigation data based on signals received by the PLD from the reflected signal receiver in form of amplitude and phase codes; and signals from angle sensors and transmission of the processed digital data over an Ethernet to the radio transmitter of the radar station.

EFFECT: reduced loss in the transceiver channel.
