SIDELOBES LEVEL IMPROVEMENT BY USING A NEW SCHEME USED IN MICROWAVE PULSE COMPRESSION RADARS

Abstract

P4 polyphase code is well known in microwave pulse compression technique. There are difierent reduction techniques to reduce the sidelobes of P4 code. This paper presents a new sidelobe reduction technique which its results are excellent. To valid our work, other sidelobe reduction techniques such as Woo fllter and modifled forms of Woo fllter are investigated and compared with the technique presented in this paper. Results show that the method introduced in this paper produces better peak side lobe ratio (PSL) and integrated side lobe ratio (ISL) than other solutions.
