On Bistatic Inverse Synthetic Aperture Radar [PDF]

IEEE Transactions on Aerospace and Electronic Systems, 2007
The use of multiple radar configurations can overcome some of the geometrical limitations that exist when obtaining radar images of target using inverse synthetic aperture radar (ISAR) techniques. It is shown here how a particular bistatic configuration can produce three view angles and three ISAR images simultaneously.

Inverse synthetic aperture radar (ISAR)

2001
Imaging of tracked moving targets is possible by applying the principles of synthetic aperture. The relative motion between the target and the fixed radar system creates this aperture. The necessary rotation of the target with respect to the line of sight amounts to only few degrees.

Inverse synthetic aperture radar imaging of satellites

International Journal of Imaging Systems and Technology, 1998
We present a scheme for radar imaging of satellites by the inverse synthetic aperture radar technique. We include some general principles in image formation when dealing with microwave-scattering experiments, such as radar observation of a satellite, so that the article is not confined to the radar community.

System compensation for inverse synthetic aperture radar

Proceedings of National Aerospace and Electronics Conference (NAECON'94), 2002
A system compensation method applied to an inverse synthetic aperture radar (ISAR) with STRETCH processing is presented in this paper. Some of the key issues causing sidelobes in ISAR design are discussed and the simulation and experiment results are given. This method can compensate not only the system distortion but the quadrature nonbalance.

Bistatic inverse synthetic aperture radar imaging

IEEE International Radar Conference, 2005., 2005
The use of a monostatic radar configuration limits the ability of an inverse synthetic aperture radar (ISAR) system to image targets in certain geometries. By employing bistatic geometries this limitation may be overcome. Bistatic radar systems will pay a great role in the coming decade since a large number of radar missions are being foreseen.
