Abstract

Embodiments of a code modulated phased-array interferometer are described. In one embodiment, a code modulated phased-array interferometer includes a phased array having a plurality of receiver elements that receive a plurality of received signals. A code multiplexer multiplexes each of the plurality of received signals to generate a plurality of code multiplexed signals, and a combiner combines the plurality of code multiplexed signals into a combined signal. After other processing for signal reception, a code demultiplexer demultiplexes the combined baseband signal, and a complex correlator correlates unique pairs of baseband signals to generate a plurality of visibility products. Finally, the plurality of visibility products are transformed to generate an image. The concepts described herein may be relied upon to reconfigure or repurpose a phased-array receiver to achieve imaging.
