Bistatic radar cross section estimation by using DDM for better spatial resolution of ocean surface wind speed

Autor: Wen-Hao Yeh, Yung-Fu Tsai, Chen-Tsung Lin

Publikováno v: Terrestrial, Atmospheric and Oceanic Sciences, Vol 35, Iss 1, Pp 1-11 (2024)

Abstract The delay-Doppler map (DDM) is the signal power distribution of the Coarse/Acquisition code (C/A code) of the received Global Navigation Satellite System (GNSS) signal in different code phase delay and Doppler frequency. When the received si

Drying Shrinkage and Mechanical Strength of Cementitious Composites with Alkali-Treated Makino Bamboo Fibers

Autor: Chin-Hao Yeh, Jyh-Horng Wu, Teng-Chun Yang

Publikováno v: Journal of Natural Fibers, Vol 21, Iss 1 (2024)

Alkali-treated bamboo fibers (AFs) treated with different NaOH concentrations (5 and 10%) and treatment times (1, 12, and 24 h) were used as fillers to fabricate cementitious composites with AFs (CAFs) in the present study. The results demonstrated t

Satellite orbit determination and time synchronization using GPS single-frequency observables in low and high solar activities

Autor: Tzu-Pang Tseng, Wen-Hao Yeh, Yung-Fu Tsai, Tung-Yuan Hsiao, Yi-Hsuan Tsai, Pei-Jung Kuo, Kun-Lin Chen, Yu-Shen Hsiao

Publikováno v: Earth, Planets and Space, Vol 76, Iss 1, Pp 1-14 (2024)

Abstract We assess the orbit accuracy and time synchronization error using the L1 and C1 observables during the different solar activities. In general, GPS single-frequency (SF) observable can be used for commercial applications in satellite industry
