1. A method comprising: receiving, using an antenna array, a plurality of radar signals comprising target echoes from a radar beam from a pulsed radar source, the antenna array comprising a plurality of individual antenna elements; sampling the radar signals at each antenna element; performing, using one or more processors, a Hermetic Transform on the plurality of radar signals comprising target echoes received by the plurality of antenna elements to produce a plurality of spatially directive beams, each beam comprising signal samples over a time period that is a multiple of the pulse repetition interval of the radar source; and using the plurality of beams to identify information about an object that is a source of the target echoes.
