An L-shaped Array with Non-Orthogonal Axes – Its Cramer-Rao Bound for Direction Finding
(IEEE, 2017-08)
If a nominally L-shaped sensor-array's two legs are not exactly perpendicular, its azimuth-polar direction-of-arrival estimation would be degraded. This paper quantifies this degradation via a deterministic Cramér-Rao ...
A Lower Bound of Estimation Error of an Emitter's Direction-of-Arrival / Polarization, for a Collocated Triad of Orthogonal Dipoles/Loops That Fail Randomly
(2017-04)
For a triad of short dipoles (or of small loops), in perpendicular orientation relative to each other but collocated in
space, this study derives a lower bound for their error in direction-of-arrival estimation and ...
