Research on High Fidelity Cluster Encrypted Transmission Method for Marine Target Detection

Abstract

A high fidelity cluster encryption transmission method for sea target detection is proposed. The disadvantage of relatively complex processors and slow encryption speed for software encryption on the ocean. The characteristics of information realtime and miniaturization in practical application can not be satisfied. This paper focuses on the fusion and encryption and coding of target information, Reliable and safe transmission of target information at sea can be achieved with high precision underwater acoustic detection module and high speed processor of FPGA and combined with RSA digital encryption algorithm. Finally, display in data terminal interface. Through simulation experiment, the test results show that the method collects the orthogonal vector underwater acoustic signal and boost underwater acoustic signal with zero time difference, and synchronized wireless transmission of signals to host computer by cluster encryption together with magnetic signals. The method can achieve high precision and high fidelity target information restoration.
