Abstract Based on the magnetic field data recorded by ZH‐1 electromagnetic satellite, we cerat a training set of 1,300 spectrograms containing dispersion spectrum lightning whistlers (LW). The Segment Anything Model (SAM) in image segmentation is trained through to obtain fine‐tuned SAM model that can be used detect and segment LW at pixel level. All track regions are effectively separated from other non‐lightning after being segmented model. effect excellent detection accuracy 96.89%, which...
Abstract China National Offshore Oil Corporation (CNOOC), Chevron, and ENI, the field operator, are partners in development of HZ oil gas fields, operating as CACT Operators Group (CACT) South Sea. The fields stacked, thin, high-permeability sandstone reservoirs interlayered with low-permeability layers. shallower layers generally have better permeability were developed first while deeper, lower-permeability been more recently. lower porosity higher compressive strength....
This paper reviews the first-ever image demoireing challenge that was part of Advances in Image Manipulation (AIM) workshop, held conjunction with ICCV 2019. describes challenge, and focuses on proposed solutions their results. Demoireing is a difficult task removing moire patterns from an to reveal underlying clean image. A new dataset, called LCDMoire created for this consists 10,200 synthetically generated pairs (moire ground truth). The divided into 2 tracks. Track 1 targeted fidelity,...
The time-to-digital converter(TDC) aims to mark an accurate timestamp at the time of input signal comes. Multi-phase Clock sampling method is usual way map TDC into FPGA. Traditionally, this provides a medium accuracy and low resources occupation. In paper, we present new architecture base on 2-ISERDES in SelectIO, rather than utilizing Slice by old way. ISERDESes based equivalent 8 equidistant phase-shifted clocks TDC, with maximum clock frequency 900MHz. least significant bit(LSB) 139ps,...

In this paper, we propose an iterative algorithm to jointly optimize transmit waveform and receive filter in signal dependent clutter for space time adaptive processing (STAP) based on airborne distributed array radar. the first place, STAP model radar is deduced, which different from that of traditional uniform linear because structural particularity radar, optimization problem formed decompose it into two sub-problems. By solving a classical minimum variance distortionless response (MVDR)...
