Abstract
As the amounts of satellite communication and radar devices increasing, the electromagnetic environment for global navigation satellite systems (GNSS) becomes more and more complex. High power radar signal in L-band has obvious interference to uplink injection of navigation satellites. If satellites has ability to detect and identify interference signals, it will be beneficial to take measures to avoid interference. For the typical linear frequency modulated (LFM) radar signal, a method based on Radon-Wigner Transform (RWT) is proposed to efficiently estimate parameters of multi-components LFM signals, and simulation is performed to verify the validation of the method. The results of this paper can be used to detect and identify the LFM radar interference for navigation satellites.
