A new high-resolution approach is presented for noise reduction in lidar signals using variable frequency resolution empirical mode decomposition. Avalanche photo diode (APD) output single-channel low signal-noise ratio (SNR) real data are decomposed into multi-scale components and reconstructed with less noise. The key to have a fine scale signal each component. Based on the non-symmetric symmetric timeline APD data, proposed highly effective distinguishing between by choosing an...
Full-waveform LiDAR systems have been developed owing to their superiority in terms of high precision and resolution. However, further improving the imaging speed resolution continues be a problem. In this study, we propose an optical orthogonal code division multiple access (OCDMA) coding 3D technique, non-scanning full-waveform system is first demonstrated. Encoding, multiplexing, decoding are essential modules OCDMA system, which use M detectors N-bits achieve high-accuracy decomposition...
Rational design of the composition and microstructure has been recognized as an effective strategy for fabricating high-efficiency electromagnetic wave (EMW) absorption materials. Herein, hierarchical FeCoNiMnCu high-entropy alloys (HEAs)/carbon nanofiber (FeCoNiMnCu/CNF) composites were fabricated by using a bottom-up synthesis method involving electrospinning followed calcination. The nanosized nanoparticles are uniformly embedded within CNF, constructing partial core–shell structures...
Three-dimensional (3D) lidar imaging technology is developing rapidly in civil, commercial, and military fields. Especially the field, with a high signal-to-noise ratio (SNR) long range essential. However, SNR contradictory to long-range detection, which difficult problem be resolved. In this paper, we propose an adjustable higher 3D-imaging cluster (C-Lidar) based on coded full-waveform technique. C-Lidar makes full use of linear mode avalanche photodiode (Lm-APD) multiplexing space-time...
Underwater imaging is an interesting and challenging topic in field of lidar due to the absorption scattering light by water, which decreases signal-to-noise ratio (SNR) effective laser echo signals thus reduces distance quality. In this paper, ultra high SNR cluster LiDAR technique for underwater targets 3D proposed. The results formula derivation calculation indicate that can be increased 10 log <tex xmlns:mml="http://www.w3.org/1998/Math/MathML"...
