A spatial cognitive radar system, method of assembling the radar, and method of selecting antenna elements in the radar are described. The system includes a phased array of a plurality of antenna elements and a plurality of receiver channels, the plurality of receiver channels being a value greater than one and less than a number of the plurality of antenna elements. The system also includes a processor to determine a subset of the plurality of antenna elements, equal in number to the plurality of receiver channels, to be used in transmitting or receiving with the spatial cognitive radar system.

Spatial cognitive radar

A system for cancelling interference in a wireless network, the system comprising apparatus for computing and outputting at least N weighting vectors; and apparatus for cancelling interference from antennae outputs received by the system using the weighting vectors respectively by converting the weighting vectors into FIR filter coefficients and applying FIR filters corresponding to the FIR filter coefficients to derivatives of antennae outputs received by the system. The apparatus for computing and outputting weighting vectors may be operative by estimating a spatial signature while distinguishing interference spatial signature from desired signal spatial signature although both are received simultaneously.
