Low-Rank Structured Clutter Covariance Matrix Estimation for Airborne STAP Radar

no code implementations27 Jan 2023 Tao Zhang, Haifang Zheng, Qijun Luo

In space-time adaptive processing (STAP) of the airborne radar system, it is very important to realize sparse restoration of the clutter covariance matrix with a small number of samples.

Finite-Time Analysis of Fully Decentralized Single-Timescale Actor-Critic

no code implementations12 Jun 2022 Qijun Luo, Xiao Li

Most of the existing finite-time convergence results are derived based on either double-loop update or two-timescale step sizes rule, and this is the case even for centralized AC algorithm under a single-agent setting.
