Title :
Discussions on RFI suppression in SAR using FRFT
fDate :
31 Aug.-4 Sept. 2004
Abstract :
In order to remove the RFI as much as possible, we should use as much information as we know about the signal and the RFI. Most methods of RFI suppression use no information of the transmitted signal. A thought for RFI suppression using FRFT is proposed in this paper. Some simulation results are given.
