Spectrum planning and performance evaluation between heterogeneous satellite networks
A new network has been recently proposed for the provision of fixed broadband services via high altitude platform stations (HAPS) in the 48/47 GHz band. One of the critical issues...

A point target reference spectrum for general bistatic SAR processing
Focusing bistatic SAR data in frequency domain requires the two dimensional (2D) point target reference spectrum (PTRS). In this paper, a 2D PTRS is derived based on Loffeld’s b...
