In order to improve the angle accuracy and meet the requirement of side‐lobe blanking, the fire‐control radar system usually adopts sum beam, azimuth difference beam, elevation difference beam and several protecting antennas simultaneously. A ΣΔG‐STAP method based on sum, difference and protecting channels is proposed to improve the performance of ground moving target detection. Moreover, the target is located on the Doppler beam sharpening image by the monopulse angle estimation technique. The effectiveness of the proposed method is verified using the simulated data and measured data.
