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:
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
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
ISE example
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)
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

CHILL has recorded great amounts of data
Here are some examples of this:
