Next steps: improve your radar
Make improvements in order of importance:
1. Proper data acquisition system with trigger – improved pulse-to pulse phase coherence
improves clutter rejection in range vs. timeimproves SAR imagery
– calibration possibleimprove SAR resolution
2. Increase reliability by soldering analog circuits on to proto board
3. Increase reliability by building into metal or plastic chassis
MIT Lincoln Laboratory ajf 2/16/2010

Next steps: build a wider bandwidth orhigher frequency radar
• Use more bandwidth to improve range resolution • Increase frequency to improve cross-range resolution • Mount on to automated rail for increased cross-range
positioning accuracy – less difficult to make SAR image – increases ‘funness’ level

Summary
• Course objective: generate interest in radar design – Abstract and difficult concept made to be fun – Lectures at a high level to keep things interesting:
history of radar RF design antennas pulse compression SAR imaging
– Continuous engagement, make actual radar system – Field experiments, results from 9/9 groups:
doppler vs. timerange vs. timeSAR imaging
• Long-term recruiting and increased campus collaboration • Course to Opencourseware site
– share with all students interested in radar – share our concept of interactive learning with greater DoD
