Summary:This letter presents the simulated design and signal processing algorithms of a novel single-transceiver compressive reflector antenna for high-sensing-capacity imaging. The compressive reflector antenna (CRA) generates a spatial code in the imaging region, which is dynamically changed by using a mechanical rotation of the reflector. The scattered data measured by the single transceiver is processed using compressive sensing techniques in order to perform a 3-D reconstruction of the object under test. Preliminary results show that the CRA outperforms traditional reflector antennas in terms of sensing capacity and reconstruction accuracy.
