ABSTRACT
One of the methods in creating disturbance in radar is to apply appealing jammer. These jammers send strong signals like target-return signals into radar. If these signals enter from main lobe of radar antenna, create false targets in different ranges. Besides if they enter from secondary lobes, radar receiver is not able to distinguish between signals entered from primary and secondary lobes, and they are interpreted as signals of primary lobes, consequently some false targets are detected in different angles. In this paper, with considering the method that is used in [Shnidman, D.A and Toumodge, S., 2002], we simulate an optimum method to block secondary lobe jammers. Lobe disturbance from primary radar signal, done by applying pulse calculations.
