Abstract
A method for interleaved pulsed-Doppler processing. Radar energy management and associated processing techniques take advantage of spatial degrees of freedom available on modern, short range, wide angle, volume search ESA radar systems. The method creates an advantage in Doppler resolution when compared to currently utilized Doppler processing techniques. An Electronically Scanned Array (ESA) radar system includes one or more processors that may be programmed to read and execute instructional commands including transmit a plurality of synchronized, coherent pulsed transmit beams having substantially repeatable gain and phase pattern characteristics; electronically steer the plurality of transmit beams in a respective, sequential plurality of spatially diverse directions in a temporally-interleaved manner; sequentially collect a respective plurality of receive beams in a respective plurality of time vs. range buffers; determine a range-Doppler output at a selected, common receive position in each of the plurality of buffers.
