To avoiding two-dimensional search for the incoming angle of jamming while constructing two-dimensional auxiliary beams, an adaptive-adaptive beamforming algorithm of planar array based on one-dimensional auxiliary beam is presented in this paper. Owing to only need to estimate one-dimensional spatial angle of jamming, computational complexity of searching for the incoming angle of jamming can be...
In this paper we introduce a batch frequency domain scheme for wideband jammer nulling with multichannel synthetic aperture radar (SAR). This is compared to the wideband extension of the SLC approach. We analyze the nulling performance for several image acquisition modes and interference scenarios and show that both algorithms are adequate in terms of cancellation level. The frequency domain approach...
