| 中文摘要: |
| 沉底目标探测实验时,相继脉冲混响之间存在非相关成分。结合混响时-频谱图分析,给出了引起相继脉冲混响之间非相关成分的影响因素。根据概率论中的大数定律,采用了一种相继脉冲混响积累抵消的方法以对非相关成分进行抑制。通过对实验数据的分析结果表明,所用方法可以抑制混响之间的非相关成分,使时-频谱图中混响背景变的更加均匀,有利于目标信号的检测。 |
| 英文摘要: |
| The data of bottom target detection show that there are non-correlated components between successive pulses reverberation.Combined with the spectrum of reverberation,some influencing factors are analyzed.According to the law of large numbers,an integrated cancellation method for suppressing the non-correlated components is proposed.The results of lake experiment show that the non-correlated components are suppressed,and the uniform background of reverberation is usually conducive to target signal detection. |
