A Novel Strategy for Radar Imaging Based on Compressive Sensing [PDF]

, 2010
Radar data have already proven to be compressible with no significant losses for most of the applications in which it is used. In the framework of information theory, the compressibility of a signal implies that it can be decomposed onto a reduced set of

Near-Space Microwave Radar Remote Sensing: Potentials and Challenge Analysis

Remote Sensing, 2010
Near-space, defined as the region between 20 km and 100 km, offers many new capabilities that are not accessible to low earth orbit (LEO) satellites and airplanes, because it is above storm and not constrained by either the orbital mechanics of ...

Beam Footprint Detection and Tracking for Non-cooperative Bistatic SAR [PDF]

Radioengineering, 2016
In non-cooperative bistatic synthetic aperture radar (SAR), the position of transmitter’s beam footprint should be detected and tracked in real-time to perform beam synchronization.

Generalized PFA for Air-Missile Borne Bistatic Forward-Looking Beam-Steering SAR With Accelerations

IEEE Access, 2018
For air-missile borne bistatic forward-looking beam-steering synthetic aperture radar (BFLBS-SAR), the receiver platform moves along a curve track due to the existence of accelerations.

Bistatic SAR Target Recognition Using Transferred Monostatic Knowledge and Cross-Domain Feature Fusion

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Bistatic synthetic aperture radar (SAR) systems offer advantages for target recognition but suffer from severe data scarcity, particularly for maritime targets, which hinders the development of data-driven deep learning methods.

Microlocal aspects of bistatic synthetic aperture radar imaging

, 2010
In this article, we analyze the microlocal properties of the linearized forward scattering operator $F$ and the reconstruction operator $F^{*}F$ appearing in bistatic synthetic aperture radar imaging. In our model, the radar source and detector travel along a line a fixed distance apart.
