Low frequency hydrophone with a frequency range of 1-300 Hz for marine seismic exploration systems has been developed. The operation principle of the hydrophone bases on the molecular electronic transfer that allows high sensitivity and low level self-noise at low frequencies (<10 Hz) to be achieved. The paper presents a stabilization method of the frequency response within the frequency range at a depth up to 30 m. Laboratory and marine tests confirmed the stated characteristics as well as the possibility of using this sensor in bottom marine seismic systems. An experimental sample of the hydrophone successfully passed a comparative marine test at Gelendzhik Bay (Black Sea) with the technical support of Joint-Stock Company (JSC) "Yuzhmorgeologiya". One of the main results is the possibility of obtaining high-quality information in the field of low frequencies, which was demonstrated in the course of field tests.
已开发出用于海洋地震勘探系统的频率范围为1 - 300赫兹的低频水听器。该水听器的工作原理基于分子电子转移，这使得在低频（<10赫兹）下能够实现高灵敏度和低水平自噪声。本文提出了一种在深度达30米的频率范围内稳定频率响应的方法。实验室和海上测试证实了所述特性以及该传感器在海底海洋地震系统中使用的可能性。在股份制公司“南方地质”的技术支持下，该水听器的一个实验样本在黑海的 Gelendzhik 湾成功通过了对比海上测试。主要成果之一是在低频领域获得高质量信息的可能性，这在现场测试过程中得到了证明。
