本公开涉及一种信号传输方法和信号传输装置。
毫米波天线为安装在移动终端上用于进行射频传输的载体，如移动终端与接收设备进行信号发送与接收，可采用毫米波天线进行信号的传输实现。
但是，毫米波天线在进行信号传输时，若是毫米波天线发射的射频信号通过人体时，在外电磁场的作用下，人体内将产生感应电磁场，会对人体造成一定的辐射损害。为避免毫米波天线发射的射频信号对人体产生辐射损耗，则需要在毫米波天线上增加检测芯片检测毫米波天线产生的感应电磁场在人体中的电磁波吸收比值(SAR，Specific Absorption Ratio)，由于毫米波天线的频段较高，毫米波天线上增加检测芯片会存在较大的损耗。
然而，降低毫米波天线的射频信号的发射功率，会使得射频信号的衰减度较高，从而，导致移动终端与接收设备的通信中断。

需要说明的是，接收设备可为移动终端进行信息交互的电子设备，如毫米波基站、毫米波测试设备等。
S30、控制目标射频收发器通过射频发射通路发射射频信号。

S22、根据检测信号确定用于发射射频信号的目标射频收发器。
此时，根据获取的检测模块输出的检测信号可以确定用于发射射频信号的目标射频收发器。具体的，当检测模块输出第一检测信号，即此时可以确定摄像头扫描状态为无遮挡，即没有用户靠近移动终端，此时根据第一检测信号确定用于发射射频信号的目标射频收发器为毫米波射频收发器，即在没有用户靠近移动终端时，通过毫米波射频收发器发射毫米波射频信号可以保证终端设备与接收设备之间信号的传输速度。当检测模块输出第二检测信号，即此时可以确定摄像头扫描状态为遮挡，即用户靠近移动终端，此时根据第二检测信号确定用于发射射频信号的目标射频收发器为SUB6射频收发器，即在有用户靠近移动终端时，通过SUB6射频收发器发射射频信号可以减少终端设备与接收设备进行信号传输时对用户造成的损伤。
