Title: The Waveform Generation and Pulse Compression Technology for Polyphase Code
Abstract: The P3, P4 polyphase codes derived from linear frequency modulazed signal are common pulse compression waveforms which have some useful properties. The generation and pulse compression of P3 and P4 codes are discussed. Two methods based on direct digital synthesis (DDS) technology for the generation of P3, P4 polyphase code waveforms are proposed and some sidelobe reduction technoiques are presented, including the classical window function amplitude weighting, the least squared amplitude and phase weighting and the post compression two sample sliding processing. Finally some simulation results demonstrate the effectiveness of the sidelobe reduction techniques.\;
