无人船舶抗噪信号接收器设计

Design of anti-noise signal receiver for unmanned ship

常规船舶信号接收器能够实现船舶信号的接收,但由于接收信号噪点较高,不适合无人船舶信号的接收,为此提出无人船舶抗噪信号接收器设计。利用10 MHz TCXO以及多次滤波方式,构建抗噪信号接收器系统结构,依托信号计算进行接收通道结构设计;基于接收器数据算法和判断指令运算方式,实现无人船舶抗噪信号接收器设计。试验数据表明,设计的无人船舶抗噪信号接收器较常规船舶信号接收器噪点率下降27.99%,适用于无人船舶信号的接收。

Conventional receives the signal receiver can realize ship, but because of the received signal noise is higher,are not suitable for unmanned ship signal receiving, therefore unmanned ship noise signal receiver design is put forward. By using 10 MHz TCXO, the structure of the anti-noise signal receiver system is constructed and the structure of the receiving channel is designed based on the signal calculation. Based on the receiver data algorithm and the method of judging instruction operation, the design of the receiver design of unmanned ship's anti-noise signal is realized. The experimental data show that the noise reduction rate of the signal receiver is 27.99% lower than that of the conventional ship signal receiver, which is applicable to the reception of unmanned ship signal.
