Blasting occupy an important position in exploitation of mineral resources. With the development of mining and Geographical Information System (GIS) in mining industry, Digital Mining (DM) and Digital Blasting are becoming the research focus and they will be an inevitable trend in the future. In order to evaluate the incidental influence caused by blasting and accomplish the simulation, a blasting...
In designing some UWB-IR (ultra-wideband impulse radio) devices, the effects of ground echoes must be taken into consideration. The dispersion of soil and roughness of ground surface are significant factors in ground echoes calculation. FDTD (finite difference of time domain) algorithms applied in ground echo simulation at present have the problems of slow speed or large errors. By using multi-pole...
HY-2 satellite is a new ocean-oriented satellite which is to monitor the dynamic ocean environment with microwave sensors to detect sea surface wind field, sea surface height and sea surface temperature. In order to correct altimeter path delay due to the atmosphere, there is a microwave radiometer (ACMR) planned to be installed in the same satellite. ACMR is a three-band nadir-sounding passive microwave...
