Abstract
A time space coherence interferometer (TSCI) system is provided. In one embodiment of the present invention the TSCI system includes an interferometer in communication with an RF source and a receiver. The interferometer includes a first switch, a second switch, a transmit element, a receive element and a sequencer circuit, wherein the sequencer circuit is configured to alternate the first and second switches between first and second configurations. In a first configuration, the signal from the RF source is provided to the transmit element, where it is communicated to the receive element via a signal path, and provided to the receiver. In the second configuration, the signal from the RF source is provided to the receiver via a reference path. The switching sequence results in a complex ratio of the signal path signal to the reference path signal (e.g., an S21 transmission ratio) being provided to the receiver.
