The application provides a UUV detection wave generation method, device, UUV and waveform generator, which relate to the field of UUV detection technology and are applied to each UUV in the UUV cluster. The method includes: generating an initial detection signal, which is generated by It consists of M sub-pulses that are orthogonal to each other, and M is a positive integer greater than 1; use the modulation sequence corresponding to the set target modulation to perform target modulation on the initial detection signal to obtain the detection wave corresponding to the UUV, where each UUV is set There is a modulation sequence corresponding to the target modulation. The modulation sequences corresponding to the target modulation in different UUVs are orthogonal to each other. The modulation sequence includes M symbols, and there is a one-to-one correspondence between sub-pulses and symbols. The detection waves corresponding to different UUVs They are orthogonal to each other. Therefore, the mutual interference between the detection waves corresponding to each UUV in the UUV cluster is avoided, and the anti-reverberation performance of the detection waves corresponding to the UUV is improved, thereby improving the detection accuracy of the UUV cluster.
Description
technical field [0001] The present application relates to the technical field of UUV detection, in particular to a UUV detection wave generation method, device, UUV and waveform generator. Background technique [0002] Unmanned Underwater Vehicle (UUV) plays an important role in the current ocean exploration, ocean development and other fields. UUV can complete specific underwater tasks in complex underwater environments. [0003] At present, when performing underwater tasks, the cooperation among the UUVs in the UUV cluster is mostly used to complete the underwater detection tasks. However, due to the scarcity of underwater spectrum resources, the detection waves of each UUV are prone to aliasing during the cooperative detection process of the UUV cluster within a limited frequency band, resulting in low accuracy of detection results. Contents of the invention [0004] Embodiments of the present application provide a method and device for generating UUV detection waves,...
