The method and the device improve the angular resolution of monopulse radars. A signal DELTA theta is initially calculated, in a computing arrangement (201), from the sum signal S, the direction signal theta b and the quadrature angular offset signal epsilon q. Two measurement signals theta A and theta B for the direction of the extreme limits of the target are furthermore calculated in a computing arrangement (202). In addition, a quality signal Q for assessing the quality of these measurements is calculated, and adaptive filtering of the measurements is carried out in a filter circuit (203) in order to obtain filtered estimates of the measurement signals DELTA theta , theta A and theta B. <IMAGE>
