Embodiment Construction
[0021] The following structural drawings and embodiments further illustrate the present invention.
[0022] A frequency coupling method for half-duplex radio stations with different frequencies in the air, which comprises the following steps:
[0023] First, set up a half-duplex radio station on the ground that matches the half-duplex radio station carried by the flying object, so that the airborne object that needs to talk can communicate with the radio that matches the ground power carried by it;
[0024] Secondly, connect the voice sending port and voice receiving port of the radio station set on the ground interactively, that is, connect the voice sending port of one radio station with the voice receiving port of another radio station through the radio access module (RIF) in the digital program-controlled switching host. , the voice receiving port of one radio station is connected with the voice transmitting port of another radio station, and a signal detection circuit is ...
