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.

GNSS-Based Phase Synchronization for Bistatic and Multistatic Synthetic Aperture Radar [PDF]
IEEE Transactions on Geoscience and Remote SensingThe feasibility of single-pass interferometric or multistatic synthetic aperture radar (SAR) mission concepts largely relies on the ability to achieve the matching of the carrier phase of the different radar instruments of the constellations within a few degrees.

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.

An investigation of a frequency diverse array [PDF]
, 2009 This thesis presents a novel concept for focusing an antenna beam pattern as a function of range, time, and angle. In conventional phased arrays, beam steering is achieved by applying a linear phase progression across the aperture.
