Moving target detection and tracking with multiplatform radar network (MRN)
IET Radar, Sonar & Navigation, 2022 A multiplatform radar network (MRN) composed of multiple transmitting and receiving facilities is advantageous over monostatic radar in moving target detection (MTD) and tracking due to the diversity gain.

Statistical Detection of Coordination in a Cognitive Radar Network through Inverse Multi-objective Optimization [PDF]
arXiv, 2023 Consider a target being tracked by a cognitive radar network. If the target can intercept noisy radar emissions, how can it detect coordination in the radar network? By 'coordination' we mean that the radar emissions satisfy Pareto optimality with respect to multi-objective optimization over the objective functions of each radar and a constraint on ...

$Radar^2$: Passive Spy Radar Detection and Localization using COTS mmWave Radar [PDF]
, 2022 Millimeter-wave (mmWave) radars have found applications in a wide range of domains, including human tracking, health monitoring, and autonomous driving, for their unobtrusive nature and high range accuracy. These capabilities, however, if used for malicious purposes, could also result in serious security and privacy issues.

Signal Processing for Tracking of Moving Object in Multi-Impulse Radar Network System
International Journal of Distributed Sensor Networks, 2015 Indoor positioning systems (IPSs) have been discussed for use in entertainment, home automation, rescue, surveillance, and healthcare applications. In this paper, we present an IPS that uses an impulse radio-ultra-wideband (IR-UWB) radar network.

Adversarial Radar Inference: Inverse Tracking, Identifying Cognition and Designing Smart Interference [PDF]
arXiv, 2020 This paper considers three inter-related adversarial inference problems involving cognitive radars. We first discuss inverse tracking of the radar to estimate the adversary's estimate of us based on the radar's actions and calibrate the radar's sensing accuracy.

Radar SLAM: A Robust SLAM System for All Weather Conditions [PDF]
arXiv, 2021 A Simultaneous Localization and Mapping (SLAM) system must be robust to support long-term mobile vehicle and robot applications. However, camera and LiDAR based SLAM systems can be fragile when facing challenging illumination or weather conditions which degrade their imagery and point cloud data.

Bernoulli track‐before‐detect smoothing for maritime radar
IET Radar, Sonar & Navigation, 2022 Detection and tracking of small targets in sea clutter using a high‐resolution radar is a challenging problem as the sea surface constantly moves in a complex manner, with rough seas creating strong target‐like returns. Recently, a Bernoulli track‐before‐
