Target Parameter Estimation via One-Bit PMCW Radar
Heng Zhu, Xiaolei Shang, Jian Li
Abstract
We consider the problem of phase modulated continuous wave (PMCW) radar signal processing when the receiver utilizes one-bit sampling with known time-varying thresholds. We formulate the target parameter estimation problem as a sparse signal recovery problem and use the alternating direction method of multipliers (ADMM) to solve it efficiently. Specifically, the log-norm approximation is used to replace the ` <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0</sub> -norm to make the optimization problem more tractable. We then judiciously design the detailed updating steps of ADMM for the log-norm approximation, so that all updating steps involve computationally efficient closed-form solutions. Numerical examples are provided to demonstrate the effectiveness of our algorithm.
