- Project Objective:
- Estimated the angle of arrival of a signal at the receiver within three degrees
- Resolved the location of a transmitter within less than five percent of the total search area
- Experimental Hardware and Software Setup:
- 6x USRP-2920 SDR
- CDA-2990 Octoclock
- 5x 3 dBi 915 MHz omnidirectional antenna
- LabVIEW Communications
- MATLAB
- Project Outcomes
- Implemented a phased array of antennas with software defined radio to estimate a signal’s angle of arrival
- Applied phase offset corresponding to a particular angle of arrival
- Found angle with maximum correlation. Test results are accurate to a single degree
- Created MATLAB script using angles from multiple receivers to determine the location of the transmission
- Used coordinates, orientation, and estimated the angle of arrival to find an intersection point
