Joint parameter estimation employing coherent passive MIMO radar

Abstract

Passive multiple-input multiple-output radar is studied for the problem of joint estimation of target location and velocity. A general case is considered, where the signals of opportunity may be non-orthogonal and the clutter-plus-noise may be correlated. The maximum likelihood estimate is provided and the Cramer-Rao bound is derived. The authors show the performance gain obtained from coherent processing and analyse the performance variation induced by the effects of signal non-orthogonality and the correlation of the clutter-plus-noise components.
