Abstract With the rapid development of unmanned technology, AUVs equipped with side-scan sonar are playing an increasingly important role in underwater detection. The detection small targets such as mines, unexploded ordnance, and poles is currently focus research technology plays a vital role, especially military combat. However, existing methods rely too heavily on priori shadow information prone to missing many targets. Therefore, we propose weighted SSS patch-image model. method improved...
Satellite altimetry can provide long-term water level time series for bodies lacking hydrological stations. Few studies have evaluated the performance of HY-2C and Sentinel-6 satellites in inland bodies, as they operated less than 1 2 years, respectively. This study measured accuracy CryoSat-2, HY-2B, HY-2C, ICESat-2, Jason-3, Sentinel-3A, Great Lakes by in-situ data 12 stations from January 2021 to April 2022. Jason-3 lowest mean root-mean-square-error (RMSE) level, which is 0.07 m. The...
Abstract The inversion of precipitable water vapor (PWV) using the Global Navigation Satellite System (GNSS) has advantages such as all-weather observation, high precision, low cost, and temporal resolution. Currently, long-term GNSS-PWV data become an important source for studying climate change. However, due to factors equipment failures, observation technology limitations, estimation model errors, missing outliers often occur in real-time or post-processed PWV time series data....
As an important technology for measuring water levels, satellite altimetry has been widely using in the lake, river, and wetland past two decades. However, waveform pollution limits its application areas with complex topography, accuracy of existing retracking algorithms need to be further improved. In this study, a new algorithm, named Improved Narrow Primary Peak Threshold Retracking algorithm (INPPTR), based on (NPPTR) is presented. This eliminates noise waveform, extracts more accurate...
We propose a multi-color UV printing technique based on the induced degradation and collapse of amorphous inverse opal structured PEGDA photonic paper, realized chromatography via multi-step with patterned masks.
As the harm of light pollution to human life and ecological systems becomes increasingly severe, control has attracted more attention. To accurately measure risk level pollution, an evaluation model was established. Firstly, four indicators that affect degree were identified, a topsis based on entropy weight method used calculate scores 9 cities for ranking comparison with actual rankings. The final result showed two rankings close, indicating is reasonable weights are as follows:...
Rewritable photonic crystal (PC) paper has the potential to significantly reduce consumption of forest resources in printing industry, while also being environmentally friendly and efficient. However, traditional PC papers based on solvent or photothermal responses can lead diffusion, which hinder accuracy. In this study, a novel rewritable compatible with pin‐printing is presented pressure‐responsive shape‐memory paper. High‐resolution be realized by both computer‐programmed 3D‐printed...
Ionospheric diurnal double maxima (DDM) is a twin-peak pattern in the ionospheric electron density/total content (TEC) during daytime. Understanding characteristics of DDM essential to study physical mechanisms ionosphere. In this paper, vertical TEC data (VTEC) 2019–2020 derived from 537 globally distributed GPS stations were used investigate phenomenon. The results reveal that occurrence rate DDMs roughly quasi-symmetrical about magnetic equator. northern hemisphere, it first increases,...
Multi-source heterogeneous satellite image time series (MSH-SITS) have become a robust way to acquire flood detection results thanks their high-resolution and wide coverage areas advantages. In this paper, we propose an extremely lightweight soft fusion-based Unet (LSFUnet) architecture for based on MSH-SITS improve the computation efficiency of existing methods. Specifically, build encoder-decoder module with residual blocks using reduced number convolution layers smaller kernel size...
The synthesis of pure needle-shaped monoclinic-Bi5O7I (m-Bi5O7I) was achieved for the first time at pH 12.2 using bismuth citrate as a Bi source under hydrothermal condition. To enhance photocatalytic activity m-Bi5O7I, S-scheme AgBr/Ag/m-Bi5O7I (denoted AAmB) constructed via photodeposition method. Significantly, AAmB exhibited excellent degradation performance towards methylene blue (MB) visible light illumination with apparent rate constants (0.01047 min-1) approximately 4 times higher...
Soil moisture (SM) is a crucial meteorological parameter affecting agricultural production and ecosystems, so accurately capturing SM significant for farm irrigation ecosystem protection. The delay Doppler maps data of the Cyclone Global Navigation Satellite System (CYGNSS) contains characteristic information related to SM, providing new observation method observation. First, CYGNSS are matched soil active passive dataset 36 km×36 km grid by nearest neighbor method. Then, random forest...
