我们在南海深海（海深３６００）进行了混响强度的测量。使用炸药量为１公斤的定深爆炸源，以悬挂在不同深度上的无方向性水听器接收混响信号。本文给出了声源和接收器深度约为４５０米、２００米、１００米时的典型深海混响波形结构。从近程混响中可区分出体积、海面和海底混响，由此能估算出海面和海底的散射强度以及深海散射层的层强。文中给出了频率为５００赫至１６千赫范围内的海面散射强度与掠角的关系（掠角范围为９度至４４度）以及频率为５００赫至８千赫范围内的海底散射强度与掠角的关系（掠角范围为３５度至７５度）不同频段的散射强度的角度依赖关系有明显的差别，这与具体界面散射的机理有关。
We measured the reverberation intensity in the deep sea of the South China Sea (3600 at sea depth). Deep explosives, explosives at 1 kg, were used to receive reverberation signals from non-directional hydrophone suspended at different depths. This paper presents a typical deep-sea reverberation waveform structure with sound source and receiver depth of about 450 meters, 200 meters and 100 meters. From the proximity reverberation, volume, sea surface and seabed reverberation can be distinguished, from which it is possible to estimate the scattering intensity of the sea surface and the seafloor as well as the layer strength of the deep-sea scattering layer. The relationship between the scattering intensity of the sea surface and the grazing angle (grazing angle in the range of 9 degrees to 44 degrees) and the scattering intensity in the seafloor between 500 Hz and 8 kHz in the frequency range of 500 Hz to 16 kHz Grazing angle relationship (sweep angle range 35 degrees to 75 degrees) There is a clear difference between the angular dependence of the scattering intensity of different bands, which is related to the specific interface scattering mechanism.
