Example Embodiment

[0019] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0020] The present invention aims to solve the shortcoming of the exposure of the node's own position caused by the location of the sound source during the information transmission process of the underwater communication node. It uses a dolphin whistle and uses a segmented hyperbolic frequency modulation imitation dolphin whistle signal The camouflage and concealed underwater communication method uses frequency shifting to perform segmentation processing on the collected bionic signals, and then demodulates the signals through the conventional spread spectrum communication signal demodulation method, thereby realizing underwater camouflage and concealed communication.

[0021] Step 1: Determine the general model of the communication system.

[0022] The general model of the camouflage concealed underwater communication method using the dolphin whistle is...

Abstract

The invention provides a camouflage hidden underwater communication device for simulating dolphin whistle. The camouflage hidden underwater communication device comprises at least two communication nodes; each communication node is composed of a signal sending module, a signal receiving module and a receiving and transmitting integrated transducer; and the signal sending module and the signal receiving module are composed of multiple modules, such as SD cards having a dolphin whistle database. The camouflage hidden underwater communication method for simulating dolphin whistle provided by the invention is simple and high in reliability; the camouflage and the security of communication information are ensured; furthermore, requirements of an underwater hidden communication system can be satisfies; simultaneously, the device in the technical scheme of the invention is convenient to realize; compared with the formed underwater communication device, the device provided by the invention has the characteristics of being small in volume and convenient to carry; and the camouflage hidden underwater communication device provided by the invention is mainly applied to underwater acoustic communication.

Description

technical field [0001] The invention relates to a camouflaged and concealed underwater communication device which simulates the sound of a dolphin whistle, and belongs to the technical field of underwater acoustic communication. Background technique [0002] After decades of development, the underwater communication network has a certain scale and has been widely used. The underwater acoustic communication network is composed of a large number of underwater Modem nodes. Generally, the underwater communication network has the following purposes: (1) information relay transmission (due to the complexity of the underwater communication channel, in order to ensure the quality of communication between the two terminals, two Underwater nodes between terminals carry out information relay transmission); (2) regional monitoring (sensors equipped with monitoring items inside or outside the node device, obtain data through sensors, and transmit the data to the main node, and the main n...
