Inverse Synthetic Aperture Radar Imaging: A Historical Perspective and State-of-the-Art Survey
Radar can obtain high spatial resolution at large operating distances, and its operation is largely independent from weather and lighting conditions. This makes it an important instrument in an ever-increasing number of applications requiring robust and ...

Joint sparsity-driven inversion and model error correction for radar imaging [PDF]
Solution of inverse problems in imaging requires the use of a mathematical model of the observation process. However such models often involve errors and uncertainties themselves. The application of interest in this paper is synthetic aperture radar (SAR)

Terahertz inverse synthetic aperture radar (ISAR) imaging with a quantum cascade laser transmitter
A coherent transceiver using a THz quantum cascade (TQCL) laser as the transmitter and an optically pumped molecular laser as the local oscillator has been used, with a pair of Schottky diode mixers in the receiver and reference channels, to acquire high-resolution images of fully illuminated targets, including scale models and concealed objects.
