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:
