Abstract

Change Detection techniques are used to detect moving targets and mitigate the heavy clutter caused by strong reflections from stationary targets in through-the-wall radar. However the jitter of antenna platform results in phase distortion of scattered radar signal and decreased the performance of micro-motion target detection. This paper proposes an antenna platform jitter compensation method based on wall envelope alignment, aiming to detect micro- motion targets behind wall. Firstly, the antenna platform jitter model is established, then wall envelope alignment is applied to compensate antenna jitter in range direction and the jitter effect in cross direction is evaluated. Simulation and experimental results demonstrate that the proposed approach can compensate antenna platform jitter, eliminate the stationary clutter and detect micro-motion targets correctly and effectively.
