The problem of multichannel synthetic aperture radar image recovery in the presence sidelobe narrow‐band interference (NBI) is addressed. NBI steering matrix accurately estimated with signal received passive mode. A beamforming technique then utilised to minimise energy loss target echoes and suppress a satisfactory level. By establishing linear model for removed, reconstructed via sparse recovery. experimental results demonstrate that proposed method can both effectively generate high resolution images.
