Dan Lu, Renbiao Wu, Zhigang Su, Wei Huang · 2007
In this paper, we proposed a space-frequency GPS anti-jamming technique with constant beamwidth. The proposed method sets up a new data model by Fourier transformation. On the basis of the new model, the optimal output SINR can be obtained by using Capon beamforming similar to the only spatial domain. Also, in order to obtain the distortless GPS signal, the beampattern with constant beamwidth is generated by focusing transformation technique.
