Spectrum Matching Analysis of Chaotic Binary Modulation Excitation Sequence for Sonar Systems

摘要：

　　Sonar system has a bell-shaped magnitude spectrum.The spectrum matching degree of excitation sequence with that of sonar system is important to increase echo energy,which is related closely with the measurement range.Binary excitation sequences modulated using chaotic series,including chaotic binary amplitude shift keying,chaotic binary frequency shift keying and chaotic binary phase shift keying,are proposed in this paper.The spectrum matching degree of the proposed excitation sequences with that of sonar system is analyzed.Sonar experiments applying SensComp 600 series instrument-grade electrostatic sensors excited with chaotic binary modulation sequences validate the analytical results.
