Patent ID: 7327304

Claim:
A microwave imaging system for capturing a microwave image of a target, comprising: a microwave source for providing microwave radiation; a microwave receiver for receiving microwave radiation; a reflector antenna array including a plurality of antenna elements, each of said antenna elements being capable of being programmed with a respective phase shift to reflect the microwave radiation towards the target in a transmit beam and reflect a receive beam of microwave illumination reflected from the target towards said microwave receiver; and a processor operable to program said plurality of antenna elements with respective first phase shifts to capture a first microwave image of the target and to program said plurality of antenna elements with respective second phase shifts to capture a second microwave image of the target, said first phase shifts and said second phase shifts of each of said respective plurality of antenna elements being different by 180 degrees; wherein said processor is further operable to minimize noise from a combination of said first microwave image and said second microwave image.
