TL;DR: In this article, a 3D radar imaging mechanism borrowing the concept of optical ghost imaging (GI) is proposed, where high range resolution is achieved by transmitting wideband electromagnetic (EM) signal, while high resolution in the orthogonal plane is obtained by correlating the echoes with radar antenna's stochastically fluctuating radiation pattern which can be generated with a 2D phased array.

TL;DR: In this paper, the authors demonstrate the benefits of the yaw steering, and then provide two aspects of the system design with the incorporation of demonstrating the benefits, such as making the 2D side-lobes nearly orthogonal, and improving the imagery quality.

TL;DR: In this paper, the authors proposed a novel digital beamforming (DBF) method for multi-modes MIMO-SAR based on APC waveforms, which can work in several modes simultaneously such as spotlight, sliding spotlight and strip map modes.

TL;DR: In this paper, the authors presented an efficient algorithm to reconstruct the signal of SF MIMO-SAR in the spotlight and sliding spotlight modes, which includes Doppler ambiguity resolving algorithm based on subaperture division and an improved frequency-domain bandwidth synthesis (FBS) method.

TL;DR: A imaging passive localization method for wideband signal by introducing synthetic aperture radar (SAR) imaging method, the location of the signal emitter is directly given in SAR image to focus unknown wideband data in range and azimuth domain.
