In this article a RADAR scanning method, based on microwave photonics was presented. The operation principle was based on an antenna array radiating on a far-field target, where the radiation spectral curve was divided so that different spatial sub resolution segments within the target area were illuminated by a different microwave frequency. Thus, although the radiation that is back reflected from those spatially sub resolution segments was mixed in the detecting single small aperture antenna, due to the frequency encoding, their detector could back separate them and could reconstruct signal with higher spatial resolving capability. Experimental and simulation results were presented for one-dimensional and two-dimensional antenna array.
