“…However, few authors have focused for jointly addressing the two problems which is reported in the literatures [14][15][16], but focus is on non-radar signal issues. In the article [17] Zadoff-Chu (ZC) phase method is applied for radar application and in this paper same is extended with SU method for reducing autocorrelation sidelobe level and maintaining low value of PMEPR. This paper is organized as follows.…”

Employing the multitone waveforms for radar applications has attracted many authors in recent days. Several researchers have investigated the use of multitone waveform and challenges associated while implementation. The serious drawback of using multicarrier waveforms is the high Peak to Mean Envelope Power Ratio (PMEPR) values recorded and large sidelobes. To overcome PMEPR and sidelobe drawbacks a novel method is suggested for reducing sidelobe levels. The projected method applies zad-off chu phase sequence for multicarrier complementary phase coded (MCPC) signals. The comparison of integrated sidelobe ratio and peak sidelobe is obtained. Autocorrelations and complex envelope of the MCPC signal is obtained from the above methods are analyzed with extensive simulations. It is also possible to reduce the PMEPR and sidelobe simultaneously by using secondary user method. The suggested technique results with reduction in sidelobe and PMEPR levels.
