J.-N. Bruneton,J.-J. Manzino,E. Caramella passing from the top boundary are selected as effective rays to tomography system in the most studies. However, a number of side signals penetrating from the side of tomography area are eliminated, which reduces the utilization of GNSS rays and aggravates the morbidity of tomographic observation eq

Radiology of Non-Spinal Pain Proceduresly used as the backup equipment for high-speed Unmanned Aerial Vehicle (UAV) in high-frequency environmental dithering condition. However, both the large-amplitude acceleration during UAV high-speed taxiing and the high-frequency environmental dithering caused by the propeller are important reasons

The simulation of GNSS-R signals mostly uses wind-driven wave spectrum, which ignoring other factors in the real ocean environment, such as the currents. Therefore, this paper proposes a method for modeling GNSS-R signal

Radiology of Occupational Chest Diseaseom the sea surface, has demonstrated unique advantages for sea level monitoring. The signal-to-noise ratio (SNR) of a geodetic GNSS receiver can be used to estimate the distance between antenna and sea surface called reflecting height (RH), and subsequently to retrieve sea level. The classical SNR a

Recently years, with the continuous development of Global Navigation Satellite System, GNSS Multipath Reflectometry technology has become one of the emerging means of snow depth measurement because of its all-weather, low cost, high spatial-temporal resolution and other advantag

Densitometry in Clinical Practice,etic surveying, but it is difficult to replace conventional leveling surveying due to height anomaly. The Fitting of Moving Quadric Surface (FMQS) is based on the known points in the circular region with the center of the point to be fitted and a specific radius. In this paper, the method of FMQS is
