Abstract
An antenna array for use within a microwave imaging system includes a plurality of reflecting antenna elements, each capable of being programmed with respective phase-shifts in a first pattern to direct a first beam of microwave radiation towards a first target, and each being capable of being programmed with respective phase-shifts in a second pattern to direct a second beam of microwave radiation towards a second target. To capture a microwave image of an object, the antenna elements are programmed with respective phase-shifts in an interleaved pattern including a portion of the first pattern and a portion of the second pattern.
Claims22
A reflector array for use in a microwave imaging system to capture a microwave image of an object, comprising:
- a plurality of reflecting antenna elements, each capable of being programmed with respective phase-shifts in a first pattern to direct a first beam of microwave radiation towards a first target, and each being capable of being programmed with respective phase-shifts in a second pattern to direct a second beam of microwave radiation towards a second target;
- wherein said plurality of antenna elements are programmed with respective phase-shifts in an interleaved pattern including a portion of said first pattern and a portion of said second pattern to capture said microwave image of said object.
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;
- and
- a reflector antenna array including a plurality of antenna elements, each of said antenna elements being capable of being programmed with respective phase-shifts in a transmit pattern to direct a beam of microwave radiation from said microwave source towards said target, and each being capable of being programmed with respective phase-shifts in a receive pattern to reflect a reflected beam of microwave radiation reflected from said target towards said microwave receiver;
- wherein said plurality of antenna elements are programmed with respective phase-shifts in an interleaved pattern including a portion of said transmit pattern and a portion of said receive pattern to capture said microwave image of said target.
A method for capturing a microwave image of a target, comprising:
- providing an array including a plurality of reflecting antenna elements;
- designing a transmit pattern of respective phase-shifts for each of the reflecting antenna elements to direct a beam of microwave radiation from a microwave source towards the target;
- designing a receive pattern of respective phase-shifts for each of the reflecting antenna elements to reflect a reflected beam of microwave radiation reflected from the target towards a microwave receiver;
- and
- programming each of the microwave antenna elements with a respective phase-shift in an interleaved pattern including a portion of the transmit pattern and a portion of the receive pattern.
