A method of spatially filtering signal parameter vector data includes receiving, at a computing device, a first signal parameter vector at a first time and a second signal parameter vector at a second time occurring after the first time. The first and second signal parameter vectors are derived from a plurality of signals received at a sensor, and include first and second signal data blocks, respectively. The method also includes transmitting, to at least a first and second element of an array data structure representative of a physical spatial domain, the first and second signal data blocks, respectively, and determining an elliptical error region probability object having a center and a pair of axes containing the first and second signal data blocks. The center represents a highest probability location of a signal emitter at the second time and the pair of axes represents the spatial error of the center.
