PROBLEM TO BE SOLVED: To provide a monopulse angle-measurement radar system, capable of processing angle measurement by improved angle resolution, even if a wide beam is used. SOLUTION: When performing monopulse angle measurement of a target by radar echo signals received by respective sum (Σ) and difference (Δ) beam patterns, the radar echo signals are received to obtain theΣandΔsignals, theΣsignal is attenuated, based on the S/N ratio of a target in theΣsignal or a rough angle measurement value, as a result of angle measurement processing using theΣandΔsignals, and the angle measurement value of a target is calculated by the ratio of the level of theΣsignal to that of theΔsignal after attenuation.
