In this paper, we have presented an X band high power amplifier based on MMIC (Monolithic Microwave Integrated Circuit) technology for satellite remote sensing systems. We have used GaN HEMT process with 500 nm gate length technology with VD= 40 V and VG= -2 V in class E structure. The proposed two-stage power amplifier provides 25 dB power gain with maximum output power of 49.3 dBm at 10 GHz. ...

As the amount of data rises and application needs expand, the efficient organization and management of remote sensing data has become a bottleneck restricting the application of remote sensing technology. The Global Partition Theory (GPT) and high performance computing provide an approach to solve the above mentioned problems. GPT studies how the Earth's surface is split into different levels o...

Remote sensing, the science of obtaining information via noncontact recording, has swept the fields of ecology, biodiversity and conservation (EBC). Several quality review papers have contributed to this field. However, these papers often discuss the issues from the standpoint of an ecologist or a biodiversity specialist. This review focuses on the spaceborne remote sensing of EBC from the pers...

   Current study monitored Electerical Conductivity (EC) as soil salinity index and Organic Matter (OM) in the area of Harat in Yazd, Iran, through remote sensing technology with high spatial and spectral resolution. The images were selected from IRS, LISS III satellites between the years 2008 and 2012. After preprocessing and analyzing the images, the relationship between parameters of (EC) an...
