Distortion in the inverse synthetic aperture radar (ISAR) images of a target with time-varying perturbed motion

IEE Proceedings - Radar, Sonar and Navigation, 2003
Large distortion in ISAR images of a moving target has been investigated and demonstrated under controlled experiments. The distortion is a result of small time-varying perturbed motion experienced by the target and is attributed to a modulation effect in the phase of the radar return from the target.

Data Collection Eclipsing Effects in the Inverse Polar Format Algorithm (IPFA) for Turntable Spotlight Inverse Synthetic Aperture Radar (ISAR) Imaging Systems

2007 IEEE Radar Conference, 2007
This paper will present the findings associated with data eclipsing effects in the inverse polar format algorithm (IPFA) for turntable spotlight inverse synthetic aperture radar (ISAR) imaging systems. Typical turntable ISAR systems illuminate a scene of interest with an electromagnetic source in order to obtain samples of the reflectivity function ...

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.

Effect Of Data Reduction On Inverse Synthetic Aperture Radar (ISAR) Image Quality And Target Shape Descriptions

Optical Engineering, 1982
This paper is a preliminary report on investigations into the effects of data reduction on inverse synthetic aperture radar (ISAR) image quality and classifier performance. The case considered here is the effect of decimating the ISAR radar returns. Decimation of the type described induces image aliasing because of the signal processing involved in ...

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 ...
