Microwave Image Reconstruction with Two-Antenna Aperture Synthesis and Spatial Antennas Separation

Abstract

Two-antenna aperture synthesis scanning doubles azimuth resolution of imaging systems. Our previously reported image reconstruction approach assumes that transmitting and receiving antennas are situated closely to each other, but in real conditions this can be violated due to antennas physical dimensions and necessity of coupling reducing. Using common approaches can cause reconstructed image distortions. This paper presents approach that takes into account antennas separation. Effectiveness of the approach is experimentally proven.
