When conformal antennas array perform angle measurement based on the approach of conventional adaptive monopulsethe curve of monopulse ratio may be seriously distorted if there is mainlobe jamming.Consequentlythe precision of the angle measurement is poor.In this paperwe propose a method of adaptive monopulse angle measurement for conformal antennas array.The conventional adaptive sum beam is formed first.Then monopulse ratio restraint is posedand the adaptive difference beam is formed.Finallythe outputs of the sum beam and difference beam are used to measure the angle.Simulation demonstrated that the proposed method can suppress the mainlobe jamming and guarantee good measurement precision of azimuth and evaluation angles.
