  1. INHS Tracking Radar ECE 445 – Team 7 4.27.06 David Grunschel Niket Nathani

  2. Introduction

  3. Proposal • Perform quick overhaul of equipment • Build hardware and software interface for tracking target position • Collect video signal to obtain wing-beat signatures • Make design safe and reliable for field work • Field test completed design

  4. Original Design Ideas • Receive position data and select with • multiplexer • Use PCI-DAS 4020 with 20 MHz analog I/O and 24 TTL I/O lines for obtaining video and position data on the same board • Modify previous ECE 445 student’s code

  5. Our project required some preliminary work…

  6. Doing What it Takes • # trailers cleaned: 1 • # trailer cabs cleaned: 1 • # pedestals erected: 1 • # ckt boards cleaned: 20 • # chassis cleaned: 4 • # cables and surfaces cleaned: many • Working ECE 445 project: • Priceless.

  7. Turning on the Control Unit

  8. Control Unit Working! (April 2)

  9. Reverse Engineering • Previous User’s Interface Cable

  10. Schematics ≠ Reality

  11. Interface Control Signals

  12. Board 1A3A5 • Data Registers • ADDR Decoder • ADDR Register

  13. Interface :: Hardware • PCI I/O Computer Board: • Measurement Computing CTR-05 • 8 TTL outputs • 8 TTL inputs • Capable of sinking 24 mA; plenty to override radar logic • Fast enough for our purpose

  14. Interface :: Software • while ( ESC key not pressed ) { • for( all 12 data bytes ) { • Initialize control signals • Set ADDR bits A1-A4 • Load ADDR • Set intermediate quad buffer to high-Z • Activate ADDR decoder • Sample data register • Measure D0-D7 • } • Convert BCD digits to AZ, EL, RA, and TIM numbers ; • Write to datafile ; • Calculate coordinates for graphics display ; • Update graphics display ; • }

  15. Interface :: Software :: Data Output File • Data output file format: • TIM AZ EL RA • 540 222.24 7.99 1372 • 541 222.24 7.99 1372 • etc. • Data file automatically saved with time • and date stamp

  16. Interface :: Software :: Graphics • Features • Real-time • Windowed • Easy-to-interpret displays • Observable motion of target • Practical scale parameters • Thanks to Jon Johnson, who • used OpenGL to write the C++ • code for the graphics display • from the detailed • specifications we gave him.

  17. Radar Controls

  18. Testing • Power Supplies • Standalone Control Unit Operation • CTR-05 Board • Logic Voltage Levels • Response to Control Signals • Real-time Software Operation

  19. Future Work • Get transmitter unit fully operational • Collect analog video signal and store • reflected power time series of target • Signal analysis of time series (Prof. Franke)

  20. Thanks to: • Ron Larkin for everything, especially his enthusiasm • Ben Kamen for his vast knowledge of electronics, the use • of his equipment, and his time and support • Jonathan Johnson for his amazing programming skills and his time • Dan Mast for advice on board cleaning and the use of his equipment • Scott Anderson and Scott Carney for their support and belief • in our abilities
