Laser Scanning (LIDAR) Co-Registration Matching Buildings
2015/12/4
When LIDAR data is considered as data source for 3D models of urban areas, there is the choice between airborne and terrestrialsystems. They have different characteristics like resolution or scene ext...
Behaviour of large scale structures of the electron content as a key parameterfor range errors in GNSS applications
parameterfor GNSS
2015/9/14
The Total Electron Content (TEC) of the ionosphere is a key parameter for describing the ionospheric state. This paper deals with the large scale behaviour of TEC under low and high solar activity con...

Analog-to-digital conversion (ADC) CMOS image sensors digital cameras dynamic range image sensors mixed analog–digital integrated circuits pixel-level ADC video cameras
2015/8/12
Analysis results demonstrate that multiple sampling can achieve consistently higher signal-to-noise ratio at equal or higher dynamic range than using other image sensor dynamic range enhancement schem...
Investigation of CMOS Varactors for High-GHz-Range Applications
Investigation CMOS Varactors High-GHz-Range Applications
2009/9/4
This paper explores a variety of different CMOS varactor structures for RF and MMICs. A typical 0.18μm CMOS foundry process was used as the study platform. The varactors' capacitance-voltage character...
Zero Crossing Counter for Accuracy Improvement of FMCW Range Detection
Zero Crossing Counter Accuracy Improvement FMCW Range Detection
2009/7/28
civil and military purposes FMCW radars are widely used. The theoretical background is well-established. Nevertheless, improvement of various aspects of these radars is still required. Signal processi...
Nondiffracting Light Beams of Long Range Propagation
Light beam Nondiffracting beam Long range propagation
2009/6/8
An unusual light beam, long range nondiffracting beam (LRNB) is presented. The LRNB propagates over a long range keeping its narrow beam width as if it does not diffract, while general light beams spr...
TERRESTRIAL LASER SCANNER POINT CLOUD DENOISING BY RANGE IMAGE NLMEANS PROCESSING FOR SMALL-SIZED OBJECTS
Terrestrial Laser Scanning Denoising Modelling Accuracy
2016/2/29
In some applications, long range operations Terrestrial Laser Scanners (TLS) achieve insufficient precision: for instance, a decorated
façade will not be modeled correctly with the point cloud ...
