Data-Driven Target Localization: Benchmarking Gradient Descent Using the Cramer-Rao Bound
Shyam Venkatasubramanian, Sandeep Gogineni, Bosung Kang +1
In modern radar systems, precise target localization using azimuth and velocity estimation is paramount. Traditional unbiased estimation methods have utilized gradient descent algo…
High Fidelity RF Clutter Modeling and Simulation
Sandeep Gogineni, Joseph R. Guerci, Hoan K. Nguyen +4
In this paper, we present a tutorial overview of state-of-the-art radio frequency (RF) clutter modeling and simulation (M&S) techniques. Traditional statistical approximation based…
How to Calibrate your Adversary's Capabilities? Inverse Filtering for Counter-Autonomous Systems
Vikram Krishnamurthy, Muralidhar Rangaswamy
We consider an adversarial Bayesian signal processing problem involving "us" and an "adversary". The adversary observes our state in noise; updates its posterior distribution of th…
Fusion of Deep Neural Networks for Activity Recognition: A Regular Vine Copula Based Approach
Shan Zhang, Baocheng Geng, Pramod K. Varshney +1
In this paper, we propose regular vine copula based fusion of multiple deep neural network classifiers for the problem of multi-sensor based human activity recognition. We take the…
Transmit MIMO Radar Beampattern Design Via Optimization on the Complex Circle Manifol
Khaled Alhujaili, Vishal Monga, Muralidhar Rangaswamy
The ability of Multiple-Input Multiple-Output (MIMO) radar systems to adapt waveforms across antennas allows flexibility in the transmit beampattern design. In cognitive radar, a p…
Semiparametric CRB and Slepian-Bangs formulas for Complex Elliptically Symmetric Distributions
Stefano Fortunati, Fulvio Gini, Maria Greco +2
The main aim of this paper is to extend the semiparametric inference methodology, recently investigated for Real Elliptically Symmetric (RES) distributions, to Complex Elliptically…
