| 27. A radar system, comprising:
a sensor to sense angular motion of a radar platform, wherein angular motion is at least one of a roll, pitch or yaw motion;
a module to compensate each array subsection response of a plurality of array subsection responses for any sensed radar platform
angular motion by applying continuous time varying phase adjustments to each individual array subsection response;
a module to determine the time varying phase adjustments in response to any sensed radar platform angular motion;
an analog to digital converter to digitally sample each array subsection response; and
a plurality of complex multiplication modules, each module for applying a phase shift to each digitally sampled array subsection
response based on any platform angular motion adjustments relative to the array subsection response.
