Distributed Target Tracking using Radar Networks
Shao-Hsuan Hung, Raj Thilak Rajan
Distributed target tracking is essential for scalable and robust sensing systems, as it enables multiple radar nodes to cooperatively estimate a target state without relying on a c…
A Covariance Matching Approach to Graph Topology Identification
Yongsheng Han, Raj Thilak Rajan, Geert Leus
Graph topology identification (GTI) is a central challenge in networked systems, where the underlying structure is often hidden, yet nodal data are available. Conventional solution…
Geometry-Aware Edge-State Tracking for Resilient Affine Formation Control
Zhonggang Li, Raj Thilak Rajan
Affine formation control (AFC) is a subset of formation control methods that enables coordinated multiagent movement while preserving affine relationships, and has recently gained…
Cooperative Sense and Avoid for UAVs using Secondary Radar
Mostafa Mohammadkarimi, Raj Thilak Rajan
A cooperative Sense and Avoid (SAA) algorithm for safe navigation of small-sized UAVs within an airspace is proposed in this paper. The proposed method relies upon cooperation betw…
On the choice of reference in offset calibration
Raj Thilak Rajan
Sensor calibration is an indispensable task in any networked cyberphysical system. In this paper, we consider a sensor network plagued with offset errors, measuring a rank-1 signal…
Multi-FEAT: Multi-Feature Edge Alignment for Targetless Camera-LiDAR Calibration
Bichi Zhang, Holger Caesar, Raj Thilak Rajan
Multi-agent systems, e.g., automobiles and UAVs (Unmanned Ariel Vehicles), rely on the precision of onboard sensors to accurately perceive their environment, which in turn depends…
Relative Kinematics Estimation Using Accelerometer Measurements
Anurodh Mishra, Raj Thilak Rajan
Given a network of static nodes in -dimensional space and the pairwise distances between them, the challenge of estimating the coordinates of the nodes is a well-studied pro…
