Operation principle：
As shown in Figure 1, power detection module detection receives the watt level of signal, ARM chips transfer power detection module
The watt level of detection, if watt level, in normal range (NR), ARM chips adjust the power of low noise amplifier module, letter
Number by low-noise amplifier processing be transferred to RF receiving and transmission module, RF receiving and transmission module is using RF agile transceivers
AD9361, the transceiver can realize the transmitting-receiving of the radio signal of 70MHz~6GHz, support bandwidth for 200Khz~
The radio signal collected is converted to digital signal and is connected with fpga chip by 56Mhz, transceiver, and fpga chip believes numeral
Number it is modulated demodulation process；If the signal power that power detection module detects is excessive, ARM chips pass through read-write register
Mode change the reception frequency point of RF receiving and transmission module chip, receiving terminal then starts the frequency sweep in range of receiving and detects signal power
Intensity, may frequency point carry out examination white silk, whether with preset value identical, and carry out by this way wireless if detecting received signal
Channel re-establishes.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
