This paper presents an amplitude-based single-channel direction finding system for automotive applications and compares its performance against two different phase-based single-channel direction finding algorithms in a complex reflecting environment (parking garage) at 2400 MHz. All three direction finding algorithms utilize a multi-element receiving antenna array placed at two locations on a vehicle. The received complex electric fields at each antenna element within the receiving antenna array are used as inputs to the three direction finding algorithms, resulting in a direction of arrival estimate. The results from this research provide insightful information on the performance of various direction finding algorithms as a function of complex reflecting environment, transmitter height, receiving antenna array location, number of receiving antenna elements and pass rate acceptance criteria.
