Inverse Extended Kalman Filter -- Part I: Fundamentals

no code implementations5 Jan 2022 Himali Singh, Arpan Chattopadhyay, Kumar Vijay Mishra

The purpose of this paper and the companion paper (Part II) is to develop the theory of I-EKF in detail.

Inverse Extended Kalman Filter -- Part II: Highly Non-Linear and Uncertain Systems

no code implementations13 Aug 2022 Himali Singh, Arpan Chattopadhyay, Kumar Vijay Mishra

The purpose of this paper and the companion paper (Part I) is to address the inverse filtering problem in non-linear systems by proposing an inverse extended Kalman filter (I-EKF).

Counter-Adversarial Learning with Inverse Unscented Kalman Filter

no code implementations1 Oct 2022 Himali Singh, Kumar Vijay Mishra, Arpan Chattopadhyay

In this paper, we address this scenario by formulating inverse cognition as a nonlinear Gaussian state-space model, wherein the adversary employs an unscented Kalman filter (UKF) to estimate the defender's state with reduced linearization errors.

Multi-target Range and Angle detection for MIMO-FMCW radar with limited antennas

no code implementations28 Feb 2023 Himali Singh, Arpan Chattopadhyay

In this context, we propose a novel multi-target localization algorithm in the range-angle domain for a MIMO FMCW radar with a sparse array of randomly placed transmit and receive elements.

Inverse Cubature and Quadrature Kalman filters

no code implementations18 Mar 2023 Himali Singh, Kumar Vijay Mishra, Arpan Chattopadhyay

Recent developments in counter-adversarial system research have led to the development of inverse stochastic filters that are employed by a defender to infer the information its adversary may have learned.

Numerical Integration

Inverse Unscented Kalman Filter

no code implementations4 Apr 2023 Himali Singh, Kumar Vijay Mishra, Arpan Chattopadhyay

In this setting, a cognitive `adversary' tracks its target of interest via a stochastic framework such as a Kalman filter (KF).
