摘要：
An efficient RADAR imaging method that is able to detect an object within an interested area. This method uses electromagnetic waves transmitted by one or many transmitters to illuminate the interested area, and then estimates the phase shift of the scattered wave of an object according to the path that the electromagnetic wave propagated. By reversing the phase of the obtained scattered signal to the transmitters' position, an image is constructed for the entire interested area according to the correlation of signals in all channels. The present method works in the frequency domain. It produces a microwave image by using the phase and magnitude of the obtained signal, or using the phase information only. Other unique features include the way it synthesizes the signals obtained in multiple channels and at multiple frequencies. Its overwhelming high efficiency makes rapid microwave imaging and real-time imaging possible.
