  2. Encoder Interface Project • Encoders are used to determine the exact rotational position for elevation or azimuth of the radar dish • The encoders will go in the platform seen here:

  3. Encoder Interface Project • The data from the encoder will be interfaced to a Xilinx FPGA • This will convert the SSI data from the encoder to data that the DSP can use • The encoders being used have a angular resolution of 0.01degrees • A circuit board will be made to interface these devices once the logic for the FPGA is complete

  4. Xilinx FPGA • The FPGA being implemented is the Xilinx Spartan 3E • Current progress has been slow, but I am beginning to program board • Programming using ISE Webpack in VHDL Specifications of Spartan 3E: • 2,160 to 33,192 logic cells • 66 to 376 I/O • External PROM • 18 x 18 multipliers • 18 kbit dual port RAM • Low cost

  5. ISE Webpack • This is the design tool kit that is provided by Xilinx • It features FPGA programming along with being able to simulated data • Problems now with being able to do at school (working on fixing it) ISE example

  6. CHILL Facility Visit • Currently, a new radar dish is being built at CHILL • Here are some pictures of the facility at this time • The top picture shows the dish that will be put up • The bottom shows the concrete where the dish will sit

  7. VCHILL (radar data) • CHILL has recorded great amounts of data • Here are some examples of this: BLIZZARD TORNADO
