Abstract

The invention discloses an underwater acoustic signal modulation and processing method for underwater robot positioning. Spread spectrum techniques are adopted, exclusive-OR operation is carried out on the communication information and the spreading code data; the carrier signal is modulated; the problems of resource waste and signal interference caused by the fact that one underwater robot uses two acoustic systems of underwater acoustic positioning and underwater acoustic communication can be solved; meanwhile, the underwater robot can be ensured to receive acoustic signals passively all thetime, under the mode, due to the fact that the question and answer mode between the system and a user is avoided, the number of the underwater robots contained in the system has no upper limit theoretically, and theoretical support and engineering application guarantee are provided for cooperative operation of the underwater robots which develop rapidly nowadays.

Description

technical field [0001] The invention relates to the technical field of underwater robots, in particular to an underwater acoustic signal modulation and processing method for positioning an underwater robot. Background technique [0002] The ocean area accounts for about 71% of the earth's surface area, and there are abundant resources in the vast space. The ocean provides important support for human survival, and its huge space and rich resources have become a strategic space for human survival and development. Underwater robot technology is one of the important technologies of marine development technology. It is more and more widely used in civil fields such as submarine topography survey, marine rescue and salvage, underwater facility inspection, and marine mineral development. In addition, underwater robots also have broad application prospects in military fields such as submarine countermeasures, channel blockade, and underwater communication disruption. [0003] Un...
