Analysis of Chaotic Binary-phase Code Based on Logistic Mapping
摘要
Abstract
According to the disadvantages of common pseudo binary-phase code, the generating scheme of chaotic binary-phase coded signal (CBCS) based on Logistic chaotic mapping is presented. Firstly, CBCS is obtained by digital measuring and intercepting chaotic sequence, which generated from Logistic chaotic mapping. Then, the correlation, insulation degree, anti-interference performance and doppler frequency sensitivity are analyzed in detail. The simulation examples show CBCS big not only is product of time-width and bandwidth signal, but also has nicer autocorrelation features. Moreover, the anti-interference performance of CBCS is better and the doppler frequency tolerance is greater, which demonstrate CBCS is an ideal radar pulse compression signal.关键词
