2-D Coherence Factor for Sidelobe and Ghost Suppressions in Radar Imaging [PDF]

, 1956
The coherence factor (CF) is defined as the ratio of coherent power to incoherent power received by the radar aperture. The incoherent power is computed by the multi-antenna receiver based on only the spatial variable.

Numerical study on signatures of atmospheric convective cells in radar images of the ocean

, 1999
Current and wind variations at the ocean surface can give rise to a modulation of the sea surface roughness and thus become visible in radar images. The discrimination between radar signatures of oceanic and atmospheric phenomena can be quite difficult ...

Broadband circular interferometric millimetre-wave ISAR for threat detection [PDF]

Advances in Radio Science, 2007
To detect threats on a person's body surface the application of millimetre-waves is possible. In order to get a view of the person from all sides either the person has to be rotated standing on a turntable (Inverse Synthetic Aperture Radar, ISAR)

ISAR Sparse Aperture Imaging Algorithm for Large Size Target

Leida xuebao, 2012
A novel algorithm for larger size target imaging in sparse aperture is presented in this paper for Inverse Synthetic Aperture Radar (ISAR). In the proposed method, azimuth compressing is done in the range frequency domain to avoid Migration Through Range

Hybrid polarimetry inverse synthetic aperture radar

IET Radar, Sonar & Navigation
Abstract The inverse synthetic aperture radar (ISAR) system exploits the movement of the target to form its high‐resolution image. Further, the multi‐polarisation acquisition in ISAR collects additional information on the target's scattering properties and surface characteristics that help to enhance the imaging capabilities of ISAR ...
