Abstract:
A method for suppressing the effect of signals that are received or sent via side lobes of an antenna of an amplitude or phase monopulse radar device, comprising:providing three illumination functions for the antenna for each measurement axis, the three illumination functions provided for position measurement of targets, three antenna functions produced from the three illumination functions for the antenna;producing a quotient between at least one of signals and signal powers that are at least one of received and sent via at least one of the first and the second antenna function of the three illumination functions for the antenna and at least one of the signal and its signal power that is at least one of received and sent via the third antenna function of the three illumination functions for the antenna;comparing the quotient with a threshold value; anddetermining whether the signal and its signal power were at least one of received and sent via a side lobe of the antenna.
