Document Number 2620002GCode Identification 0WY55WSR-88D ROCTBDDUAL POL - DRAFT3.2.3.1 Digital Radar Data3.2.3.1.1 Message Type 1Digital Radar Data message format is provided in Table III. The message consists of base datainformation, that is, reflectivity, mean radial velocity and spectrum width, azimuth angle, elevationangle, cut type, scanning strategy and calibration parameters. The frequency and volume of themessage will be dependent on the scanning strategy and the type of data associated with thatscanning strategy.3.2.3.1.2 Message Type 31Digital Radar Data message format is provided in Table XVII. The message consists of base datainformation, that is, reflectivity, mean radial velocity, spectrum width, differential reflectivity,differential phase, correlation coefficient, azimuth angle, elevation angle, cut type, scanning strategyand calibration parameters. The frequency and volume of the message will be dependent on thescanning strategy and the type of data associated with that scanning strategy.3.2.3.2 RDA Status DataRDA Status Data message format is provided in Table IV. The message contains information aboutthe current RDA state, system control, operating status, scanning strategy selected, performanceparameters such as transmitter power and calibration and alarms. Alarms contained in this messageare summarized in Table IV-A. The RDA Status Data message is sent upon wideband connection,following state or control changes, at the beginning of each volume scan and after an RPG request.3.2.3.3 Performance/Maintenance DataThe Performance/Maintenance Data message format is provided in Table V. ThePerformance/Maintenance Data message contains status of RDA sub-functions such as the receiver,transmitter and antenna/pedestal. The RDA sends this message upon wideband connection, at thebeginning of each volume scan and after an RPG request.3.2.3.4 Console MessageThe Console Message format is provided in Table VI. When the RDA sends this message to the RPG,the Message Type indicated in the Message Header is 4. When the RPG sends this message to theRDA, the Message Type indicated in the Message Header is 10. The Console Message consists of anASCII text string composed by the system user to communicate with other RDA, RPG or RMS users.The RDA sends the Console Message upon selection by the system user.3.2.3.5 Volume Coverage PatternThe Volume Coverage Pattern message format is provided in Table XI. When the RDA sends thismessage to the RPG, the Message Type indicated in the Message Header is 5. When the RPG sendsthis message to the RDA, the Message Type indicated in the Message Header is 7. The RDA sendsthe Volume Coverage Pattern message upon wideband connection and at the beginning of eachvolume scan.3.2.3.6 RDA Control CommandsThe RDA Control Commands message format is provided in Table X. The message containscommands to select RDA state, control, operating mode, channel and volume scan strategies.3-8
Document Number 2620002GCode Identification 0WY55WSR-88D ROCTBDDUAL POL - DRAFT3.2.3.7 Clutter Censor ZoneThe Clutter Censor Zone message format is provided in Table XII. The message contains range,azimuth and elevation information for operator defined clutter censor zones. When the RDA receivesa Clutter Censor Zone message, the Clutter Filter Map message is recomputed and transmitted tothe RPG.3.2.3.8 Request for DataThe Request for Data message format is provided in Table XIII. The message allows an RPGoperator to request RDA Status Data, Performance/Maintenance Data, Clutter Filter Bypass Map,Clutter Filter Map, RDA Adaptation Data and Volume Coverage Pattern Data.3.2.3.9 Loop Back TestThe Loop Back Test message format is provided in Table VIII. When the RDA sends this message tothe RPG, the Message Type indicated in the Message Header is 11. When the RPG sends thismessage to the RDA, the Message Type indicated in the Message Header is 12. The Loop Back Testmessage transmits a sequence of bit data to verify RDA to RPG communication. The RDA sendsMessage Type 11 to the RPG upon wideband connection. After receipt, the RPG re-sends MessageType 11 to the RDA without any modifications. The RPG sends Message Type 12 to the RDA uponwideband connection. After receipt, the RDA re-sends Message Type 12 to the RPG without anymodifications.3.2.3.10 Clutter Filter Bypass MapThe Clutter Filter Bypass Map message format is provided in Table IX. The Clutter Filter BypassMap contains information about which range bins are designated as clutter for the designatedelevation segment and azimuth angle. When the RDA generates a new clutter bypass map, theClutter Filter Map message is recomputed and transmitted to the RPG.3.2.3.11 Clutter Filter MapThe Clutter Filter Map message format is provided in Table XIV. The Clutter Filter Map containsthe combined clutter censor zone information and clutter bypass map information. The RDA sendsthe Clutter Filter Map message upon wideband connection and whenever there is a change to theClutter Filter Map. When the RDA generates a new clutter bypass map or receives new cluttercensor zone information, the Clutter Filter Map message is recomputed and transmitted to the RPG.3.2.3.12 Adaptation DataThe Adaptation Data message format is provided in Table XV. The Adaptation Data messagecontains system parameters used by the RDA to determine alarm thresholds, signal processingparameters, and system configuration. The RDA sends the Adaptation Data message upon widebandconnection and whenever there is a change to the data.3-9
