Description
技术领域technical field
本发明属于水下目标探测技术领域，尤其涉及一种水下声磁电一体化目标探测装置、方法及应用。The invention belongs to the technical field of underwater target detection, and in particular relates to an underwater acoustic, magnetoelectric and integrated target detection device, method and application.
背景技术Background technique
目前，被动探测水下目标主要是利用目标产生的各种物理场，如声场、磁场、电场等。但在低信噪比、多干扰、强对抗环境下，传统单一物理场探测手段普遍存在难可靠识别、易被环境干扰虚警、易被人为对抗失效等缺陷。尤其是近年来随着各类目标的隐身性能大幅提升，目标的声、磁、电等物理场强度越来越低，检测越来越困难；同时人工模拟干扰等水下对抗手段也愈加丰富，单一物理场的特征更容易被人为模拟，使得传统单一物理场探测手段的上述缺陷更加突出。At present, the passive detection of underwater targets mainly uses various physical fields generated by the target, such as sound field, magnetic field, electric field, etc. However, in the environment of low signal-to-noise ratio, multi-interference, and strong confrontation, the traditional single physical field detection methods generally have defects such as difficult to reliably identify, easy to be falsely alarmed by environmental interference, and easy to be invalidated by artificial countermeasures. Especially in recent years, as the stealth performance of various targets has been greatly improved, the physical field strength of targets such as acoustics, magnetism, and electricity has become lower and lower, making detection more and more difficult; at the same time, underwater countermeasures such as artificial simulation interference have become more abundant. The characteristics of a single physical field are easier to be artificially simulated, which makes the above-mentioned defects of the traditional single physical field detection methods more prominent.
目标的声、磁、电场的产生来源和机理不同，在一定的时空范围内是同时存在的，如声的主要来源是目标的振动辐射噪声、螺旋桨的旋转噪声等，磁的主要来源是目标铁磁性结构在地磁场中的磁化等，电的主要来源是目标不同材料之间的电化学腐蚀等。对同一个目标，同时观测其声、磁、电场信号特征可以获得比单声/单磁/单电更多的信息，这些信息是同源的，可以相互印证、相互补充，有利于提高对目标的检测概率。而环境干扰往往不具有这种时间上和空间上的同一性，也就更容易区分目标和干扰，更不容易发生虚警。此外，由于目标声、磁、电场的产生机理不同，很难被人为地同时消除，而且通过人为模拟目标的声、磁、电场特征对探测进行干扰也就更加的困难，甚至于受空间、能源、成本等限制，是不可能同步实现的，从而使得对目标的声磁电一体化探测在防止人为消除和人工模拟干扰等手段影响探测方面具有更大的优势。总之，水下声磁电一体化目标探测装置同时利用了目标的声场、磁场和电场信息，不是孤立的利用某一种物理场，而是把三场看成一个整体，利用多场特征的耦合性和互补性实现水下目标可靠探测，具有低虚警、低漏检、抗海洋环境干扰或人工模拟对抗干扰能力强等特点。The sources and mechanisms of the acoustic, magnetic and electric fields of the target are different, and they exist simultaneously within a certain space-time range. The main source of electricity is the electrochemical corrosion between different materials of the target, such as the magnetization of the magnetic structure in the geomagnetic field. For the same target, observing its acoustic, magnetic and electric field signal characteristics at the same time can obtain more information than single sound/single magnetic/single electric. detection probability. However, environmental interference often does not have this identity in time and space, so it is easier to distinguish between targets and interference, and it is less likely to cause false alarms. In addition, due to the different generation mechanisms of the target's acoustic, magnetic, and electric fields, it is difficult to be artificially eliminated at the same time, and it is even more difficult to interfere with the detection by artificially simulating the acoustic, magnetic, and electric field characteristics of the target. , cost and other constraints, it is impossible to achieve synchronously, so that the integrated detection of the acoustic magnetoelectricity of the target has a greater advantage in preventing artificial elimination and artificial simulation interference from affecting the detection. In short, the underwater acousto-magnetic-electric integrated target detection device simultaneously utilizes the acoustic field, magnetic field and electric field information of the target, instead of using a certain physical field in isolation, it regards the three fields as a whole and utilizes the coupling of multi-field characteristics It has the characteristics of low false alarm, low missed detection, strong resistance to marine environment interference or artificial simulation anti-interference ability, etc.
通过上述分析，现有技术存在的问题及缺陷为：现有的水下目标探测装置，只使用一种物理场，如声探测或者磁探测或者电探测。单一物理场探测信息有限(如图4中只有一条曲线的信息)，存在难可靠识别、易被环境干扰虚警、易被人为对抗失效等缺陷，不能满足人们在日益普遍的低信噪比、多干扰、强对抗环境下对水下目标进行可靠探测的需求。Through the above analysis, the existing problems and defects of the prior art are: the existing underwater target detection devices only use one kind of physical field, such as acoustic detection or magnetic detection or electrical detection. The detection information of a single physical field is limited (as shown in Figure 4, there is only one curve information), and there are defects such as difficult reliable identification, easy to be disturbed by the environment, false alarms, and easy to be artificially counteracted. Reliable detection of underwater targets in multi-interference and strong confrontation environments.
解决以上问题及缺陷的难度为：单一物理场探测信息有限(如图4中只有一条曲线的信息)，低信噪比的情况下很容易漏报，环境干扰较多的情况下又很容易虚警，而且单一的物理场也容易被人为的模拟相应的特征，导致对抗失效。The difficulty in solving the above problems and defects is: the detection information of a single physical field is limited (the information of only one curve in Figure 4), it is easy to miss the report in the case of low signal-to-noise ratio, and it is easy to make a false report in the case of a lot of environmental interference. Moreover, a single physical field can easily be artificially simulated with corresponding characteristics, resulting in the failure of confrontation.
解决以上问题及缺陷的意义为：本发明可以同点同时利用目标的声、磁、电等多个物理场的信息(如图4中的3条曲线)，可以获得更多的目标特征，而不会因某一种物理场信息出现偏差导致整个目标探测的任务失败。目标声、磁、电等多类信息彼此之间可以相互印证、相互补充，信息越多结果越准确可靠，从而在低信噪比下有利于提高对目标的检测概率。而环境干扰往往不具有这种时间上和空间上的同一性，也就更容易区分目标和干扰，更不容易发生虚警。此外，由于目标声、磁、电场的产生机理不同，很难被人为地同时消除，而且通过人为模拟目标的声、磁、电场特征对探测进行干扰也就更加的困难，甚至于受空间、能源、成本等限制，是不可能同步实现的，从而使得对目标的声磁电一体化探测在防止人为消除和人工模拟干扰等手段影响探测方面具有更大的优势。The significance of solving the above problems and defects is: the present invention can simultaneously utilize the information of multiple physical fields such as sound, magnetism and electricity of the target at the same point (as shown in 3 curves in Figure 4), and can obtain more target features without The entire target detection task will fail due to a deviation in a certain type of physical field information. Various types of information such as target acoustic, magnetic, and electrical information can be confirmed and supplemented with each other. The more information, the more accurate and reliable the result, which is conducive to improving the detection probability of the target under low signal-to-noise ratio. However, environmental interference often does not have this identity in time and space, so it is easier to distinguish between targets and interference, and it is less likely to cause false alarms. In addition, due to the different generation mechanisms of the target's acoustic, magnetic, and electric fields, it is difficult to be artificially eliminated at the same time, and it is even more difficult to interfere with the detection by artificially simulating the acoustic, magnetic, and electric field characteristics of the target. , cost and other constraints, it is impossible to achieve synchronously, so that the integrated detection of the acoustic magnetoelectricity of the target has a greater advantage in preventing artificial elimination and artificial simulation interference from affecting the detection.
