Effects of Bandwidth Limitation on Polyphase Coded Pulse Compression Systems
The effects of both pre- and postcompression bandwidth limitations on frequency-derived polyphase-coded pulse compressors are illustrated. Such band limitation is found to decrease the peak to maximum range-time-sidelobe ratios of the Frank and P3 coded compressor outputs but to significantly increase the ratio using the P1, P2, and P4 codes. The band limited P1, P2, and P4 coded systems were found to produce peak to maximum sidelobe ratios close to those of so-called perfect codes such as the Barker codes without restrictions on pulse- compression ratios.
