Micro-motion indication of human target is widely used in civil and military applications. In through-the-wall (TTW) scenarios, human echo is usually heavily blurred by clutter. This Letter proposes a sparse and low-rank matrix decomposition based micro-motion indication method to indicate human targets using UWB TTW radar. The slow-time range matrix is decomposed into a low-rank matrix corresponding...
Life signal detection of human beings behind an obstacle is a keen research topic in recent years. In this paper, a singular spectrum analysis (SSA) based human life signal detection approach is proposed. SSA is a nonparametric spectral estimation method, and is widely used in time series analysis. SSA can decompose a time series into a sum of components, such as trend, periodic components and noise,...
Human target indication and detection are widely used in military and civil applications. For stationary human targets behind an obstacle, the micro-motion caused by vital sign results in a fairly low signal-to-clutter-and-noise (SCNR). This study presents an iterative singular vector decomposition (ISVD) based micro-motion indication method for detecting human targets with through-the-wall radar...
