Joint DOD and DOA Estimation for NLOS Target Using IRS-Aided Bistatic MIMO Radar
IEEE Transactions on Vehicular TechnologyIntelligent Reflecting Surface (IRS) offers new insight into Multiple-Input Multiple-Output (MIMO) radar systems, since it enables a MIMO radar to positioning targets from Non-Line-of-Sight (NLOS) directions.

IEEE Transactions on Antennas and Propagation, 1978
Empirical data have been obtained from which estimates of the bistatic reflection coefficient \sigma_{0} have been determined. Measurements were made on two terrain types (grassy terrain and an area of tall weeds and rough ground) at low grazing bistatic angles of 70\deg, 75\deg, 80\deg , and 85\deg , and 0\deg to 180\deg azimuth angle. The terrain was

ABSTRACT Through the use of an image ground plane, measurements of scattering patterns for objects with at least one plane of symmetry have been made. Until recently, only the magnitude of the patterns were available. Now the system's capability has been expanded to include accurate phase information.

Azimuth Migration-Corrected Phase Gradient Autofocus for Bistatic SAR Polar Format Imaging
IEEE Geoscience and Remote Sensing Letters, 2021A polar format algorithm (PFA) as a high-efficient imaging method is widely used in bistatic spotlight synthetic aperture radar (SAR). In cases where motion error causes great defocusing in PFA images, phase gradient autofocus (PGA) is suitable for ...
