Quantitative evaluation of scaling factor on coordinate transformation for time-of-flight terrestrial laser scanner [PDF]

, 2019
Terrestrial laser scanning is a new approach in three-dimensional measurement. Since the acquisition of terrestrial laser scanner data requires multiple scanning stations to complete the data of a scanned object, the coordinate transformation process is ...

A Novel High-Squint Spotlight SAR Raw Data Simulation Scheme in 2-D Frequency Domain

Remote Sensing, 2022
Raw data simulation is the front-end work of synthetic aperture radar (SAR), which is of great significance. For high-squint spotlight SAR, the frequency domain simulation algorithm is invalid because of the range-azimuth coupling effect.

Hybrid Mode Control of an Asymmetric Dual Three-Phase Synchronous Motor Under Single-Phase Open Fault

IEEE Access, 2022
This paper proposes hybrid mode control for an asymmetric dual three-phase synchronous motor (ADTP-SM) with separated neutral points in a single-phase open-fault situation. The fault-tolerant control is classified into the maximum torque mode and minimum
