Microwave radiometer measurements are used to extract snowpack information. However, the coarse spatial resolution of satellite brightness temperature observations hinders snow depth retrieval algorithm development and other applications. Measurements therefore require better spatial resolution to improve snow depth retrieval with enhanced resolution and accuracy. In this paper, a linear unmixing...
The coarse spatial resolution of microwave radiometer measurements hinders its application on land and sea surface parameters estimation. Measurements therefore require better spatial resolution to improve parameters estimation with enhanced resolution and accuracy. In this paper, a linear unmixing method is presented to downscale brightness temperatures (TB) for accurate land surface parameters retrieval...
In this paper, a terahertz (THz) imaging scheme with real-time capability is proposed based on frequency- controlled beam scanning. The scheme holds a concise system architecture comprising a frequency scanning reflector antenna (FSRA) as the transmitting antenna, an omnidirectional antenna as the receiving antenna, and a vector network analyzer as the transceiver. By employing the diffraction enhancement...
