KaSPR​ ​(Ka-band​ ​Scanning​ ​Polarimetric​ ​Radar) Stony​ ​Brook​ ​University FCC​ ​Experimental​ ​License​ ​Application​ ​Narrative FCC​ ​Form​ ​442​ ​File​ ​Number:​​ ​0900-EX-CN-2017. Updated:​​ ​December​ ​14,​ ​2017. Purpose of operation: An experimental FCC license is requested for operation of KaSPR, an advanced weather radar, by the School of Marine and Atmospheric Sciences at Stony Brook University. Stony Brook University​ ​is​ ​part​ ​of​ ​the​ ​State​ ​University​ ​of​ ​New​ ​York,​ ​an​ ​agency​ ​of​ ​the​ ​State​ ​of​ ​New​ ​York. Stony Brook University will use the KaSPR for environmental, climate, and meteorological research. The KaSPR is the most sophisticated cloud radar ever built and the first of its kind at a US University. The KaSPR will collect unique observations in clouds and precipitation and is expected to push our frontiers in basic knowledge​ ​in​ ​ice/snow​ ​microphysics​ ​and​ ​warm​ ​clouds​ ​lifecycle. Supplementary​ ​details: 1. Transmitter:​ ​Ka-band​ ​Scanning​ ​Polarimetric​ ​Radar​ ​(KaSPR)​ ​custom​ ​built​ ​by​ ​ProSensing,​ ​Inc.​ ​of Amherst​ ​MA​ ​USA.​ ​ ​Previously​ ​operated​ ​by​ ​US​ ​Department​ ​of​ ​Energy​ ​under​ ​authorization​ ​of​ ​NTIA Chapter​ ​1,​ ​Part​ ​1.1,​ ​serial​ ​number​ ​DOE​ ​114017.​ ​ ​One​ ​(1)​ ​unit,​ ​experimental. 2. Transmit​ ​frequency​ ​35290​ ​MHz.​ ​ ​Frequency​ ​tolerance:​ ​less​ ​than​ ​0.001%. 3. RF​ ​Output​ ​Power​ ​at​ ​the​ ​transmitter​ ​terminals:​ ​1.7​ ​kW,​ ​emission​ ​P0N,​ ​Bandwidth​ ​30.00​ ​MHz. 4. Pulse​ ​width​ ​variable​ ​from​ ​50​ ​nanoseconds​ ​to​ ​13​ ​microseconds.​ ​PRF​ ​variable​ ​up​ ​to​ ​10KHz. 5. Parabolic​ ​antenna​ ​beamwidth​ ​0.5​ ​degrees.​ ​Antenna​ ​gain​ ​50.7​ ​dB. 6. Fixed​ ​location​ ​at​ ​South​ ​P​ ​Lot,​ ​Stony​ ​Brook​ ​University​ ​Main​ ​Campus,​ ​Stony​ ​Brook​ ​NY​ ​USA. Geographic​ ​coordinates​ ​40​ ​degrees​ ​53​ ​minutes​ ​50​ ​second​ ​North​ ​Latitude,​ ​73​ ​degrees​ ​7​ ​minutes​ ​38 seconds​ ​West​ ​Longitude. 7. Antenna​ ​mounted​ ​on​ ​top​ ​of​ ​shipping​ ​container​ ​containing​ ​KaSPR​ ​electronics.​ ​Tip​ ​of​ ​antenna​ ​less​ ​than 6​ ​meters​ ​above​ ​ground​ ​level.​ ​ ​Elevation​ ​of​ ​ground​ ​at​ ​antenna​ ​site:​ ​49​ ​meters. RF​ ​Hazard​ ​Site​ ​Safety​ ​Measures: 1. Brookhaven​ ​National​ ​Laboratories​ ​RF​ ​Safety​ ​Group​ ​will​ ​be​ ​involved​ ​in​ ​all​ ​operations​ ​to​ ​ensure​ ​that​ ​no persons​ ​are​ ​subjected​ ​to​ ​RF​ ​power​ ​density​ ​levels​ ​exceeding​ ​the​ ​Maximum​ ​Permissible​ ​Exposure (MPE)​ ​limits​ ​of​ ​Part​ ​1.1310​ ​of​ ​the​ ​FCC​ ​Rules​ ​and​ ​and​ ​the​ ​guidelines​ ​in​ ​FCC’s​ ​OET​ ​Bulletin​ ​Number​ ​65. An​ ​RF​ ​Safety​ ​Control​ ​Plan​ ​will​ ​be​ ​in​ ​place​ ​for​ ​all​ ​operations.​ ​ ​The​ ​Plan​ ​will​ ​define​ ​the​ ​controls​ ​and procedures​ ​required​ ​to​ ​prevent​ ​personnel​ ​exposure​ ​to​ ​levels​ ​exceeding​ ​the​ ​MPE.​ ​ ​To​ ​verify​ ​the​ ​safety of​ ​personnel,​ ​an​ ​RF​ ​survey​ ​will​ ​be​ ​performed.​ ​ ​All​ ​measured​ ​levels​ ​where​ ​personnel​ ​have​ ​access​ ​must be​ ​below​ ​the​ ​MPE​ ​limits​ ​before​ ​operations​ ​can​ ​proceed.
