Soil Moisture Content (SMC) plays an important role in different environmental studies. In this study, to assess SMC, a method based on reflectance values in red and NIR bands from HJ-1B is introduced. This model divides SNIR-R into three separate regions based on the pixels NDVI values and fits three different regression equations to each region. All the achieved results showed that as NDVI values...
Compared with super-heterodyne architecture, one of the advantages of the low-IF receiver is that the image rejection is realized by I/Q signal processing instead of a fixed analog filter, making it highly integration, flexibility and cost-efficient. However, unavoidable imbalances between the I-branch and Q-branch lead to insufficient image attenuation which must be enhanced by using additional analog...
