Angle of Incidence Detection

Team Members: Chris Bridges and Gary Porres

Project Adviser: Dr. Kent A. Chamberlin

Problem Definition

•Determine the angle of arrival of an RF signal.

Proposed Solution•Design a receiver capable of detecting the angle of

arrival of an RF transmission

•Two antennas offset by angle

•Receiver circuit

•Calibrated code in LabVIEW

Objectives

•Have two directional antennas receive a signal and have it output a signal level

•Have labVIEW calculate the angle of arrival

•Position the antennas for best results

Implementation Plan

•Directional Antennas

•Yet-to-be determined angle

Receiver

•Coaxial Cable

•PCB with RF detector and scaling circuitry

•A/D converter

Software•LabVIEW

Testing Plan

•Position of Antennas

•Angle

Receiver

•Crosstalk

•Receiver Circuit

Anechoic Chamber
