Polarisation variation of linear polarised Bi‐ISAR system in space targets imaging

open access: yesIET Radar, Sonar & Navigation, 2021
A bistatic inverse synthetic aperture radar (Bi‐ISAR) system is used to observe space targets through different viewing angles via a bistatic radar configuration. It is seen that the receiver of a linear polarised Bi‐ISAR system with a long baseline will
