26. AIS Automatic Identification System is a shipborne broadcast system that can act like a transponder operating in the VHF Maritime band It is capable of handling over 5000 reports per minute and updates as often as every two seconds The information is coded and the system allows exchange of the information among all the ships operating in the same area The system is based on the VHF channel RX one and TX the other and uses Self Organising Time Division Multiple Access SOTDMA technology to meet this high broadcast rate and ensure reliable ship to ship data exchange Every channel is divided into time slots During these slots information related to the ship and information from other ships in the area are exchanged Each AIS system consists of one VHF transmitter two VHF TDMA receivers one VHF DSC receiver and a standard marine electronic communications link to shipborne display and sensor systems Position and timing information are normally derived from an internal or external global navigation satellite system e g GPS receiver including a medium frequency differential GNSS receiver for precise position in coastal and inland waters Other information broadcast by the AIS if available is electronically obtained from shipborne equipment through standard marine data connections The information exchanged come in two main groups Static and Dynamic data Static information does not require a high refresh rate Name Call sign Tonnage D

29. Enhancement Target Enhancement video processing is used to enhance the visibility of radar echoes By stretching them in azimuth and in range and increasing their brightness The range stretching is made only for the small echoes and not for the landmasses or rain blocks of video Target enhancement works after the anti sea rain processing and with an additional sweep to sweep control to filter the noise and sea rain clutter residuals This is made so that only the smaller echoes are enhanced in dimension and brilliance The size enhancement action is more visible on lower range scales 3 4 SART SEARCH AND RESCUE TRANSPONDERS VIDEO PRESENTATION The SART Search And Rescue Transponder is used for emergencies The range for detection of a SART is normally about 8 NM and its signal may be triggered by any X Band Radar Its purpose is to locate distressed vessels by displaying a series of echoes on the X Band Radar display of a hypothetic rescue ship Upon receiving a pulse from a standard 9 GHz X band Radar the SART immediately transmits a response which is swept repetitively across the complete Radar frequency band The response is made by a first rapid sweep 0 4 us through the band and a relatively slow sweep 7 5 us through the band back to the starting frequency repeated for a total of twelve complete cycles At some point in each sweep the SART frequency will match the one of the interrogating Radar and being within the pass band of the
