Zusammenfassung:This paper presents a new pulse compression technique that can reduce sidelobes significantly. The code used in this is p4, which belongs to the class of polyphase codes. This retains the merit of strong resistance to the Doppler shift effect. This processing technique, which is proposed in this paper, is useful to reduce peak sidelobe level (PSL) and integrated sidelobe level (ISL) but increases the mainlobe width. The results are compared with the Woo filter.
