Efficient Multiplatform Motion Error Calibration Using Strong Scatterers With Position Uncertainty in Asynchronous Airborne Distributed Radars

IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.
This work addresses the problem of multiplatform motion error calibration (multiplatform position and velocity errors) in an asynchronous airborne distributed radar network with the employment of ground strong scatterers (SSs) at inaccurate locations.

An Innovative Internal Calibration Strategy and Implementation for LT-1 Bistatic Spaceborne SAR

Remote Sensing
Bistatic and multistatic SAR technology, with its multi-dimensional, ultra-wide swath, and high-resolution advantages, is widely used in earth observation, military reconnaissance, deep space exploration, and other fields.

Bistatic multi‐polarimetric synthetic aperture radar coherence investigation using spatially variant incoherence trimming

IET Radar, Sonar &Navigation, Volume 18, Issue 12, Page 2564-2580, December 2024.
Synthetic Aperture Radar (SAR) Coherent Change Detection (CCD) allows for the detection of very small scene changes. For space‐based platforms, rapid repeat passes may have significant differences, or baselines, which can lead to decorrelations. This work investigates the sources and levels of incoherence associated with bistatic SAR imagery using ...

Performance analysis of ground‐based long baseline radar distributed systems for space situational awareness

IET Radar, Sonar &Navigation, Volume 18, Issue 4, Page 586-597, April 2024.
Detection of space objects is a key component of space situational awareness, which could help prevent and minimise space collisions. The authors focus on the feasibility of long baseline multistatic radars; and the performance of the system for a target at different altitudes and receiver configurations.

High‐resolution inverse synthetic aperture radar imaging of satellites in space

IET Radar, Sonar &Navigation, Volume 18, Issue 4, Page 544-563, April 2024.
High‐resolution ISAR imaging of objects in space supports comprehensive space surveillance. The presented IoSiS radar system achieve a spatial resolution in the centimetre range, which has not been achieved before. Abstract In view of the increasing number of space objects, comprehensive high‐quality space surveillance becomes ever more important ...

Bistatic Experiment Using TerraSAR-X and DLR’s new F-SAR System [PDF]

, 2008
A bistatic X-band experiment was successfully performed early November 2007. TerraSAR-X was used as transmitter and DLR’s new airborne radar system F-SAR, which was programmed to acquire data in a quasi-continuous mode to avoid echo window ...
