Adaptive Moving Target Detection for Forward Scatter Radar When the Noise Power Mismatch Occurs
Electronics Letters, Volume 61, Issue 1, January/December 2025.1. The problem of detecting moving targets with forward scatter radar is discussed. 2. The noise power mismatch, namely, the noise power in the secondary data and the noise power in the primary data differing by a noise‐scaling factor, is considered. 3.

Polarisation variation of linear polarised Bi‐ISAR system in space targets imaging
IET Radar, Sonar & Navigation, 2021 A bistatic inverse synthetic aperture radar (Bi‐ISAR) system is used to observe space targets through different viewing angles via a bistatic radar configuration. It is seen that the receiver of a linear polarised Bi‐ISAR system with a long baseline will

Bistatic scattering forward model validation using GNSS-R observations [PDF]
arXiv, 2019 In this paper we advance a previously developed bistatic scattering forward model to include the circularly polarized incident and scattered waves, which is the case for Global Navigation Satellite System (GNSS) reflectometry. This model development enables retrieval of soil moisture from Signals of Opportunity (SoOp) bistatic observations, e.g., from ...

Classification of unarmed/armed personnel using the NetRAD multistatic radar for micro-Doppler and singular value decomposition features [PDF]
, 2015 In this letter, we present the use of experimental human micro-Doppler signature data gathered by a multistatic radar system to discriminate between unarmed and potentially armed personnel walking along different trajectories.

IET Microwaves, Antennas &Propagation, Volume 19, Issue 1, January/December 2025.In this paper, we propose a three‐dimensional integral equation‐based GSTC solver for the electromagnetic analysis of metasurface composite structures. We present a novel numerical method, focusing on the rigorous enforcement of boundary conditions at the interfaces, a critical aspect in the problem formulation for composite structures.
