The Radiometric Measurement Quantity for SAR Images [PDF]
A Synthetic Aperture Radar (SAR) system measures among other quantities the terrain radar reflectivity. After image calibration, the pixel intensities are commonly expressed in terms of radar cross sections (for point targets) or as backscatter ...

In this article, we provide a Gaussian beam‐based method to compute the RCS of dielectric and dielectric‐coated targets in both the monostatic and bistatic cases. ABSTRACT This study proposes to extend and refine the methodology of Gaussian beam summation (GBS) for computing the radar cross section (RCS) of dielectric targets in both monostatic and ...

A Concept for High Performance Reflector-Based Synthetic Aperture Radar [PDF]
The success of current spaceborne Synthetic Aperture Radar (SAR) is boosting the performance requirement of next generation systems. In order to cope with the evolution of SAR, the design of the new systems will need to meet higher requirements for ...

Moving targets often appear defocused and displaced in SAR imagery, complicating detection and recognition—especially when displaced into cluttered regions, where signal‐to‐background ratio is reduced. This work presents a multistatic SAR framework that extracts moving target signatures and reconstructs focused images, providing new insights into the ...

Characterisation and Classification of Resident Space Objects Using Radar Networks
This paper describes a simulated environment for generating Inverse Synthetic Aperture Radar (ISAR) images and interferometric point clouds using a three‐receiver radar configuration, along with the creation of extensive datasets to train and evaluate deep learning models under varying Signal‐to‐Noise Ratio (SNR) conditions. Findings show that modified

Bi- and Multistatic SAR: Potentials and Challenges [PDF]
Bi- and multistatic synthetic aperture radar (SAR) operates with distinct transmit and receive antennas which are mounted on separate platforms. Such a spatial separation has several operational advantages which will increase the capability, reliability ...

This paper presents a multistatic, frequency‐ and polarimetry‐adaptive autofocus algorithm (F‐Pol) for SAR imaging of moving targets undergoing complex, six‐degrees‐of‐freedom (6‐DoF) motion. Building on Localised Threshold Sharpness (LTS), the method exploits agreement across frequency sub‐bands and polarisation channels to improve pulse‐by‐pulse ...

Multi‐Angle Bistatic Scattering Characteristics of Ground Targets Observed by GB‐SAR Experiment
This paper presents an experimental investigation of bistatic scattering characteristics using an outdoor ground‐based SAR system working in Ku‐band. Representative artificial and natural targets were measured and analysed to characterise their angular bistatic scattering responses and underlying scattering mechanisms.
