The Driver Of Remote Control Underwater Basing On Vector Sensor

Due to the special characteristics of underwater remote control system, the system has been become an important researched content of underwater equipment. Underwater acoustic channel is typical parameter channel. With the influence of multifrequency diffuse and correlational banwidth and so on, it is very difficult for receiving and processing of underwater acoustic signal. Especially, interference of domino effect of neritic multifrequency is the most important factor in the dependable decode of underwater remote control system..Firstly, for the characteristics of neritic multifrequency signal environment, the paper has researched the ways the coding and decode accordingly. The ways that adopt the means of frequency-shift can confront the interference effectively between one code and another in the embracer. Secondly, the paper has discussed the strength of the polarization diversity reception of the combined receiver. The combined receiver is consisted of three velocity sensors and a pressure sensor, which co-locating and simultaneously measures the pressure and three orthogonal components of the particle velocity. 6dB directivity gain could be obtained using the optimal weighted pressure and particle velocity in isotropic noise field. Basing on the simulation, it shows that the results of the polarization diversity reception are better than the pressure's and the sound intensity's.In the end, the paper has introduced the exploided situation of hardware and software system is not steady, then it does not realized the function of decode correctly. So, hardware development is the same important status in the whole system. The hardware system has regarded TMSVC3205509DSP as core component which classify and realize the operation of polarization diversity reception and adaptative filter.
