摘    要:针对用主动声纳探测水下高速运动的小目标存在的主要干扰,海面,海底混响和接收信号的起伏,讨论了宜采用的声纳信号形式,在混响信道中,对高多普勒目标采用加窗的长CW脉冲是合适的,而根据多途信道中回波存在的起伏的特点,需要采用多频脉冲,最后给出了用探测高速小目标的声纳最佳发射信号形式和频率编码方案。

关 键 词:主动声纳  波形设计  混响  多途  声纳  高速目标

Abstract:Because of the main interference while detecting a high speed small target using an active sonar,the appropriate sonar signal waveform is discussed in this paper. It is proper to use windowed long CW pulses to restrain the reverberation from sea interfaces,and multi frequency pulses must be adopted for there exists transmission fluctuation of sound signal in a multi path clannel.At last,a suitable sonar signal waveform and the frequency coding scheme are presented.
Keywords:active sonar  waveform design  reverberation  multipath
