Radar Imaging with EISCAT 3D [PDF]
Annales Geophysicae, 2020 Abstract. A new incoherent scatter radar called EISCAT 3D is being constructed in Northern Scandinavia. It will have the capability of producing volumetric images of ionospheric plasma parameters using aperture synthesis radar imaging. This study uses the current design of EISCAT 3D to explore the theoretical radar imaging performance and compares ...

An Imaging Plane Calibration Method for MIMO Radar Imaging. [PDF]
Sensors (Basel), 2019 In two dimensional cross-range multiple-input multiple-output radar imaging for aerial targets, due to the non-cooperative movement of the targets, the estimated imaging plane parameters, namely the center and the posture angles of the imaging plane, may have deviations from true values, which defocus the final image.

Parameter Estimation for Interrupted Sampling Repeater Jamming Based on ADMM
Sensors, 2021 By repeatedly sampling, storing, and retransmitting parts of the radar signal, interrupted sampling repeater jamming (ISRJ) based on digital radio frequency memory (DRFM) can produce a train of secondary false targets symmetrical to the main false target,
