Noise Removal in Near Range Active Millimeter Wave Three-dimensional Imaging System
Aimed at the noise removal in near range active millimetre wave pulse linear frequency modulation (LFM) based three-dimensional imaging system, this paper proposes a novel noise removal algorithm, which combines the independent component analysis (ICA) and Wigner-Hough transform. The algorithm is effective in noise suppression and easy to implementation. In a semi-physical simulation system, the algorithm improves the signal-to-noise ratio (SNR) of the echo signal by 10dB in standard target imaging experiment which verifies the effectiveness and feasibility of the noise removal algorithm.
