1. Electrical Noise Location System Drew Compston Brandon Denney Josh Gordon

2. 2 29 November 2007 Original Project Goals Display Information about AM Spectrum in GUI Identify Angle of Arrival of Strong AM Signals Build Noise Sources to Test System Estimated Total Cost to be $16,228 Noise Source Noise Receiver Computer: Displays GUI and Calculates AoA

3. 3 29 November 2007 Original Software Goals Connect Computer with Receiver (QT-400) Plot QT-400 Output in Easy to Use GUI Calculate Angle of Arrival (AoA) Computer Wireless Router RF Receiver (QT-400)

4. 4 29 November 2007 Problems Connecting to QT-400 Two Faulty Units Received over Semester Third Unit Had Incompatible Firmware Hidden Proprietary Code Created Software Implementation Issues

5. 5 29 November 2007 Graphical User Interface PhaseAB = 97.319 PhaseBC = 163.2 RSSIA = 105.23 RSSIB = 96.32 RSSIC = 104.67 Our only doorway into QT-400!

6. 6 29 November 2007 Graphing QT-400 Data Original Idea: Use Open Source Software  Missing Library Files  Error-Ridden Code  Uncommented/Lacked Documentation  Demos of Software for Purchase New Idea: Graph Using Matlab R2007a.NET Plug-in

7. 7 29 November 2007 Original Plan: Calculate AoA According to Consistently Received Signals with R C ≈ R A When R C ≈ R A, Ψ ’ ≈ 45° Conclusion: Not Receiving Strong Signals from Any One Direction Progress in Computing AoA

8. 8 29 November 2007 Testing with Noise Source Create Sinusoids at 1MHz, 1.54MHz, and 1.84MHz with Signal Generator Create Noise Signal with Broadband Random Noise Generator Step Up Signal Strength with Power Amplifier Broadcast Signals with Simple Antenna

9. 9 29 November 2007 Sine Wave Output

10. 10 29 November 2007 Obstacles to Marketability Lack of Plotting Capability Product Cannot Be Fully Tested without Stronger Noise Sources Algorithm Currently Inaccurate ANY QUESTIONS?
