An eigenvector approach for inverse synthetic aperture radar (ISAR) motion compensation and imaging
TENCON '97 Brisbane - Australia. Proceedings of IEEE TENCON '97. IEEE Region 10 Annual Conference. Speech and Image Technologies for Computing and Telecommunications (Cat. No.97CH36162), 2002 Inverse synthetic aperture radar (ISAR) is a high resolution imaging radar. The image reconstruction of ISAR involves two steps; motion compensation and image formation. In this paper, an eigenvector approach is proposed to carry out ISAR motion compensation.

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 ...

RF-Driver and Waveform System of X-band inverse synthetic aperture radar (ISAR)
2012 International Conference on Microwave and Millimeter Wave Technology (ICMMT), 2012 Inverse synthetic aperture radar (ISAR) is an important branch of the synthetic aperture radar (SAR). It has ability of high-resolution imaging on distant targets, so it has great potential for long-range goals. This article discusses the method of RF-Driver and Waveform System on X-Band Inverse Synthetic Aperture Radar (ISAR), analysis of the ...

Data Visualization for Low-Frequency Inverse Synthetic Aperture Radar (ISAR)
International Journal of Interdisciplinary Telecommunications and Networking, 2018 The purpose of this article was to use ISAR to determine the distance between the receiving antenna and the transmitting antenna. Once a systematic approach has been determined, this article could be used on a spacecraft to locate debris in the path of the carrier.

An Efficient Basis for Decomposition of Cavity Returns in Inverse Synthetic Aperture Radar (ISAR) Measurements Using Basis Pursuit [PDF]
2019 International Conference on Electromagnetics in Advanced Applications (ICEAA), 2019 We recently described a technique called basis pursuit dictionary editing (BDPE) that uses L1 minimization techniques to remove contamination from ISAR measurements and imagery of rotating targets [1]. While our original BPDE technique works well when the target scattering is dominated by literal (non-interacting) returns, non-literal target scattering,

, 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.

SPIE Proceedings, 1981 This paper is a preliminary report on investigations into the effects of data reduction on 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 ISAR image formation.

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 ...
