海豚声纳信号的脉冲分解及特征分析.提出一种海豚声纳目标探测脉冲串信号的脉冲分解方法,在此基础上对海豚声纳脉冲信号的特征进行了分析,其中包括脉冲宽度、脉冲间隔以及脉冲的时间分辨率和频率分辨率,并采用耳蜗滤波对海豚声纳脉冲串信号的时频特征进行了分析。分析结果表明,探测目标的过程中,根据目标距离的不同,海豚会自适应调节脉冲信号的发射频率和信号形式。 -Dolphin sonar signal pulse decomposition and characteristics of proposed burst signal of a dolphin sonar target detection pulse decomposition method, on the basis the dolphin sonar pulse characteristics of the signal was analyzed, including pulse width, pulse interval pulse time resolution and frequency resolution, and cochlear filtering on the the dolphin sonar pulse train signal when the frequency characteristics of the analysis. The analysis results show that the process of the probe target, depending on the target distance, dolphins adaptive adjusting the transmission frequency and the signal form of the pulse signal.
