Abstract :
This paper shows how a triad of orthogonally oriented uniaxial velocity sensors may be spatially separated, yet facilitate direction finding of incident emitters via closed-form subspace-based parameter estimation algorithms, while extending the triad´s spatial aperture in three-dimensional space to enhance the resolution of the azimuth/elevation direction of arrival estimates.
