Abstract:

The constraints of pattern nulling and the prototype equiripple finite impulse response (FIR) are respectively added to the original fourier transform frequency invariant beamforming (FIB) to obtain pattern of wideband FIB with low sidelobe and anti-jamming nulling. The thinned optimization of FIB coefficients is also considered to reduce the calculating complex. The simulation results verify the correctness and effectiveness of the proposed method.
