All other embodiments, which can be made by those skilled in the art based on the embodiments of the present application without making any inventive effort, shall fall within the scope of the present application.
The terms "first," "second," "third," and "fourth" and the like in the description and in the claims and drawings are used for distinguishing between different objects and not necessarily for describing a particular sequential or chronological order. Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may include other steps or elements not listed or inherent to such process, method, article, or apparatus.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.
The core device of the underwater acoustic communication system is a transducer. The underwater acoustic transducer is a transducer device that converts other forms of energy into acoustic energy for radiating underwater or converting a received underwater acoustic signal into a signal of other forms of energy. The underwater acoustic communication has low speed and large time delay compared with the electromagnetic communication, wherein the main technical bottleneck for limiting the speed is the working bandwidth of the underwater acoustic transducer. The operating bandwidth of the underwater acoustic transducer is several orders of magnitude lower than conventional electromagnetic communication bandwidth.
Currently, conventional underwater acoustic transducers are all based on ceramic materials with piezoelectric effect, such as early barium titanate ceramics, lead zirconate titanate ceramics (PZT), rare earth giant magnetostrictive material ternary alloys (Terfenol-D), relaxation ferroelectric single crystal materials (PZN-PT, PMN-PT) and the like. In addition, there are also composite acoustic transducers today, such as type 1-3 piezoelectric composites, which are two-phase piezoelectric composites composed of one-dimensional interconnected piezoelectric phase pillars arranged in parallel in a three-dimensional interconnected polymer phase matrix. The main purpose of the continuous improvement of the material is to improve the key indexes such as the piezoelectric performance, the working bandwidth and the like of the energy converter.
In general, the above-described transducer material development still follows the technological lines of piezoelectric materials. The piezoelectric material is essentially a solid phase material, and the piezoelectric performance, the working bandwidth and the matching performance are all limited by the mechanical properties of the solid phase material. Therefore, the current different application scenarios (not only underwater communication, but also underwater acoustic imaging, submarine topography mapping and the like) all have transducers with specific frequency bands, and the transducers can be generally divided into low-frequency transducers, medium-frequency transducers, high-frequency transducers or ultrasonic transducers and the like. Even if the communication is underwater acoustic communication, different communication requirement conditions (high speed, medium speed and low speed) all need transducers with different bandwidths and a modulation and demodulation system matched with the transducers, so that the system is huge and complex.
In order to solve the technical problems, the invention provides an ultra-wideband adjustable sound source technology based on in-water discharge plasma, which comprises the following specific steps:
