Abstract
A radar system located on an antenna array mounted on a moving carrier and including plurality of antenna elements; a transmitter portion coupled to the antenna and configured to transmit a plurality of transmit beams, each including a corresponding orthogonal transmit waveform of a plurality of orthogonal transmit waveforms, each of the plurality of transmit beams having a transmit phase center spatially located at a respective point along the antenna array, the transmitter portion being configured to transmit each transmit beam during at least a portion of a pulse repetition interval, wherein the transmitter portion is configured to shift the transmit phase center of each transmit beam for each pulse repetition interval to a respective point along the antenna array in a direction opposite the movement of the carrier, such that a speed of the respective transmit phase center of each beam remains is reduced.
