The information from the components obtained by waveform decomposition is usually used to inverse topography, and classify tree species, etc. Many efforts on algorithms have been presented, but they lack comparison analysis evaluation. Thereby, this article compares analyzes performance of five algorithms, which are Gaussian, Adaptive Weibull, Richardson–Lucy (RL), Gold, under different topogra...

Many studies have established the strong connections between aboveground biomass and lidar height metrics; however, these relationships are site-specific. Field data required to derive not readily available in many cases. We developed a model estimate plot-level density (AGBD) directly from large-footprint waveform measurements. An individual tree-based (AGB)-height allometric relationship was ...

A summary overview about the types of lidar and their own applications on atmosphere detection is presented. Measurement of atmospheric aerosols by Mie lidar and Raman lidar is focused. The vertical profiles of aerosols in the atmosphere are retrieved. And at the same time, through analyzing aerosol vertical content distribution, the atmosphere boundary layer and the cloud are also observed. Al...

Design, simulation and optimal selection of cosine-linear frequency modulation waveform (CNLFM) based on correlated ambiguity function (AF) method for the purpose of Synthetic Aperture Radar (SAR) is done in this article. The selected optimum CNLFM waveform in contribution with other waveforms are applied directly into a SAR image formation algorithm (IFA) and their quality effects performance ...

Multi-channel airborne full-waveform LiDAR is widely used for high-precision underwater depth measurement. However, the signal quality of data unstable due to influence background light, dark current noise, and complex transmission process. Therefore, we propose a nonlocal encoder block (NLEB) based on spatial dilated convolution optimize feature extraction adjacent frames. On this basis, coupl...
