A signal subspace method is derived for the active array localization of point targets whose collective scattering is Born-approximable. The method enables the localization of up to N(N + 1)/2 − 1 targets from a single snapshot of the multistatic response matrix (MRM) measured by an active coincident array of N co-located transmitters and re ceivers. Furthermore, when applied to MRM data gathered using more general, noncoincident arrays of N elements, the method can be used to locate up to N2 − 1 targets. The paper includes computer simulations illustrating the theory.
