Abstract
A two-way coded aperture radar imaging system is disclosed. The system includes an antenna reflector and a radar signal transceiver configured to generate sequential radar transmission signals and receive a plurality of respective reflected radar signals. The system also includes a phase control component configured to phase-encode the sequential radar transmission signals via a plurality of phase-codes to generate a respective plurality of phase-coded radar pulses that are concurrently reflected at a respective plurality of sub-aperture portions of the antenna reflector to concurrently transmit the plurality of phase-coded radar pulses from the antenna reflector to a target. The transmitted phase-coded radar pulses can be reflected from the target as the respective plurality of reflected radar signals. The system further includes a sub-aperture radar controller configured to integrate the plurality of reflected radar signals and to generate a three-dimensional image of the target from the integrated plurality of reflected radar signals.
