1. A scanning panel for use in a microwave imaging system to capture a microwave image of a target, comprising:

  • a plurality of antenna elements, each capable of being programmable with a respective phase delay to direct a transmit beam of microwave illumination toward the target, and each being capable of receiving reflected microwave illumination reflected from the target in a receive beam, said plurality of antenna elements including;

    a first array of antenna elements arranged to direct the transmit beam of microwave illumination in a transmit beam pattern, anda second array of antenna elements arranged to receive the receive beam in a receive beam pattern complementary to said transmit beam pattern;

    wherein the microwave image of the target is formed at an intersection of said transmit beam and said receive beam, and wherein said intersection is the volume-integrated cross-product of said transmit beam and said receive beam.
