Signal-to-noise ratio adjusts power adjusting component parameter in conjunction with the transmission power that itself feeds back, and realizes that electromagnetic spectrum umbrella cover jammer discharges
The power control of interference.
10. a kind of electromagnetic spectrum umbrella cover jammer self-interference signal power control system according to claim 9 realizes function
The method of rate control, it is characterised in that: electromagnetic spectrum umbrella cover authorization electromagnetic wave device carries out electricity to the electromagnetic wave signal received
Before magnetic frequency spectrum umbrella cover self-interference inhibits, need to carry out the machine to the electromagnetic wave signal received according to the information from transmitter
Self-interference inhibits.
