Student Projects with Wes Swartz for 2000-2002

Design of a digital pulse coding system for radars

http://people.ece.cornell.edu/wes/Projects

Digital RF pulse forming can now be accomplished with new high-speed frequency synthesizing integrated circuits. Phase coding of pulsed radars is a way to improve their resolution and this design is to take advantage of the new technology for improving the accuracy of various forms of pulse coding. The circuit is to be built on a printed circuit that can be programmed by a PC to generate the low level RF as well as its phase encoding.

There are a number of integrated circuits from Analog Devices that should provide most of the functionality. (See part numbers below.) Prototyping boards with these ICs may be available (we should check).

Specific tasks:
