TenDSuR: Tensor-Based 4D Sub-Nyquist Radar
Siqi Na, Kumar Vijay Mishra, Yimin Liu +2
We propose Tensor-based 4D Sub-Nyquist Radar (TenDSuR) that samples in spectral, spatial, Doppler, and temporal domains at sub-Nyquist rates while simultaneously recovering the tar…
A Cognitive Sub-Nyquist MIMO Radar Prototype
Kumar Vijay Mishra, Yonina C. Eldar, Eli Shoshan +2
We present a cognitive prototype that demonstrates a colocated, frequency-division-multiplexed, multiple-input multiple-output (MIMO) radar which implements both temporal and spati…
Dictionary Learning for Adaptive GPR Landmine Classification
Fabio Giovanneschi, Kumar Vijay Mishra, Maria Antonia Gonzalez-Huici +2
Ground penetrating radar (GPR) target detection and classification is a challenging task. Here, we consider online dictionary learning (DL) methods to obtain sparse representations…
Cognitive Radar Antenna Selection via Deep Learning
Ahmet M. Elbir, Kumar Vijay Mishra, Yonina C. Eldar
Direction of arrival (DoA) estimation of targets improves with the number of elements employed by a phased array radar antenna. Since larger arrays have high associated cost, area…
Information Geometric Approach to Bayesian Lower Error Bounds
M. Ashok Kumar, Kumar Vijay Mishra
Information geometry describes a framework where probability densities can be viewed as differential geometry structures. This approach has shown that the geometry in the space of…
