摘要
根据主动声纳方程,进行了混响背景下主动探测声纳的性能预报,讨论了主动探测声纳工作频率对作用距离的影响,比较了不同混响反向散射强度下主动探测声纳作用距离的变化情况。分析结果表明,混响背景下主动探测声纳的作用距离随频率的降低而减小;随着混响反向散射强度的减小,主动声纳性能增强,作用距离增大,这对工程实际中更好地选取主动声纳参数,进而提高主动探测声纳性能具有一定的参考意义。
According to active sonar equation,we predict the performance of active detection sonar under reverberation,discuss the influence of the frequency of active detection sonar on the detection range,and compare the detection ranges of the active sonar under different reverberation backscattering strength.The results show that the detection range of the active sonar decreases with decreasing frequency,and the performance of the active sonar enhances and the detection range extends with the weakening of reverberation backscattering strength.This study may be useful for selecting pa-rameters of active detection sonar to enhance its performance in engineering.
