•Newtonized orthogonal matching pursuit-based compressive spherical beamforming (NOMP-CSB) in spherical harmonic domain is proposed.•The multiple-frequency synchronous version of NOMP-CSB is further developed, and MF-NOMP-CSB is proposed.•Both NOMP-CSB and MF-NOMP-CSB can effectively overcome basis...
