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.
