针对高频电磁波在空气-水界面处存在剧烈反射,以及在水中传播时衰减迅速等问题,提出以507 kHz中波为载波信号,实现陆基控制平台与水下航模的无线电通信。该系统以MSP430单片机为控制核心,采用HT6221编码技术实现陆基控制平台的按键编码,经过OPA561放大后由L型天线发射输出;采用CD9088专用调频电路,实现水下航模的无线电信号解码,经过单片机处理后,将直流电机控制信号通过红外光波通信方式发送给水面传动单元;水面传动单元采用PID算法控制直流电机牵引水下航模实现上升、下潜和深度定位等基本功能。实验结果表明:电磁波有效通信距离为10 m以上,误码率小于2%,水下航模定位精准,系统具有较强的抗干扰能力。
