Performance limits for maritime Inverse Synthetic Aperture Radar (ISAR) [PDF]

, 2013
The performance of an Inverse Synthetic Aperture Radar (ISAR) system depends on a variety of factors, many which are interdependent in some manner. In this report we specifically examine ISAR as applied to maritime targets (e.g. ships). It is often difficult to get your arms around' the problem of ascertaining achievable performance limits, and yet ...

Terahertz inverse synthetic aperture radar
(ISAR) imaging with a 
quantum cascade laser transmitter

Optics Express, 2010
A coherent transceiver using a THz quantum cascade (TQCL) laser as the transmitter and an optically pumped molecular laser as the local oscillator has been used, with a pair of Schottky diode mixers in the receiver and reference channels, to acquire high-resolution images of fully illuminated targets, including scale models and concealed objects.

Migration through Resolution Cell Correction and Sparse Aperture ISAR Imaging for Maneuvering Target Based on Whale Optimization Algorithm—Fast Iterative Shrinkage Thresholding Algorithm [PDF]

Sensors
Targets faced by inverse synthetic aperture radar (ISAR) are often non-cooperative, with target maneuvering being the main manifestation of this non-cooperation.

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 ...

Ship Target Imaging in Airborne SAR System Based on Automatic Image Segmentation and ISAR Technique

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
The airborne synthetic aperture radar (SAR) image of ship target will be blurred for the complex motion of the target, which will influence the performance of feature extraction and target classification.

Battle damage assessment using inverse synthetic aperture radar (ISAR)

, 2004
An imaging radar, like ISAR, offers a combatant the capability to perform long range surveillance with high quality imagery for positive target identification. Extending this attractive feature to the battle damage assessment problem (BDA) gives the operator instant viewing of the target's behavior when it is hit.

Multiview ISAR Imaging for Complex Targets Based on Improved SBR Scattering Model

International Journal of Antennas and Propagation, 2021
A novel multiview inverse synthetic aperture radar (ISAR) imaging method is proposed to simulate high-resolution and identifiable ISAR image of complex targets by handling large-angle and wide-bandwidth scattering data.
