A sensor array testbed for source tracking algorithms

This paper describes the University of Wyoming Source Tracking Array Testbed, UW STAT. This system was specifically developed to perform experimental evaluation of source tracking algorithms which use high-resolution direction finding algorithms in conjunction with an updating of the signal or the noise subspace after each snapshot. The array is a six element uniformly spaced linear array. The UW STAT is a compact testbed and allows for precision source motion. The motion is controlled by a motor and the angular position is recorded by an encoder, thus allowing for a direct comparison of the tracking algorithm's performance with the true position recorded by the encoder. Initial experimental tracking results presented in the paper demonstrate the tracking performance.
