Research Progress of Inverse Synthetic Aperture Radar (ISAR) Imaging of Moving Target via Quadratic Frequency Modulation (QFM) Signal Model

2019
ISAR imaging of dynamic target is very significant in real applications. Plenty of available outcomes have been acquired by the scholars in the near years. Considering the accuracy and the computational complexity, the radar echo can be described as multicomponent QFM signal after envelope alignment with initial phase calibration.

Sub-Terahertz Inverse Synthetic Aperture Radar (ISAR) for monitoring of high-value space assets 

With the rise of commercial constellation implementation in low earth orbit (LEO), the near-Earth space environment is becoming increasingly challenging to monitor and protect. As well as carefully considered policy frameworks, new observational techniques and instrumentation are needed to ensure that safe operations can be maintained by all space ...

Space-based sub-terahertz Inverse Synthetic Aperture Radar (ISAR) image formation and orbital assessment for monitoring of geostationary assets

The Pervasive Sensing group at the University of Birmingham is exploring in-orbit conditional monitoring of satellites using inverse synthetic aperture radar (ISAR) as a technique for dedicated observation of high-value space-based assets. In this work, the feasibility of geostationary orbit (GEO) observation by optimising monitoring satellite orbital ...
