Side lobe blocking apparatus and method

Abstract

A side lobe blocking method for blocking side lobe signals in a side lobe blocking apparatus may be provided. The side lobe blocking method includes setting a sum channel and a plurality of different difference channels using a plurality of receiving beams and a main beam in which a target exists among the plurality of receiving beams; calculating a plurality of different monopulse ratios using ratios between each of the plurality of different difference channels and the sum channel; determining whether a main beam target is received in a main lobe based on each of the plurality of different monopulse ratios; and finally detecting whether the main beam target is received in the main lobe based on results determined based on each of the plurality of different monopulse ratios.
