Problems solved by technology

[0010] From the perspective of the time axis, for the interfered target, it will only be interfered at a certain moment, and the time is discontinuous, and there is no interference effect in a large number of time periods; Each frequency point only interferes for a very short time, and more than 99% of the targets cannot form interference. The frequency band reservation cannot be achieved in the entire frequency band.

Abstract

The invention discloses a wideband multicarrier adaptive radio frequency interference system. The system comprises an operating console, an interference signal source, an interference transmitter, an feed system, a power supply system and the like. The interference method of the system comprises the following steps: a detection receiver inputs the corresponding radio-signal frequencies of the detected target interference frequency band in an interference waveform data generating device; the interference waveform data generating device sets the corresponding interference signal frequency points and generates control information according to the received radio-signal frequency and also generates interference waveform data; then the control information and interference waveform data are transmitted to the interference signal source and processed by a baseband signal source module to generate intermediate frequency analog signals, the analog signals are filtered and transmitted to a converter module, the converter module moves the filtered signals to the corresponding frequency band of radio frequency and then transmits the signals to a power amplifier for power amplification; and then the signals are sent to an antenna through a feeder line and then transmitted to the space for interfering the target signal. The system has high energy utilization rate and can perform continuous interference to the target signal.

Description

technical field [0001] The present invention relates to a radio frequency interference technology, in particular to a broadband multi-carrier adaptive radio frequency interference system. Background technique [0002] With the development of wireless communication technology, on the one hand, the wireless frequency resources expand the frequency band range, and on the other hand, the new technology greatly improves the frequency band utilization rate. The wireless frequency interference technology in the field of information security puts forward higher requirements. Self-noise interference technology has been difficult to meet the requirements of radio frequency interference. [0003] The technical solution of the prior art one, the noise interference method: [0004] Noise is a random signal, which is not continuous interference from the time axis. It also has random characteristics for the target signal that needs to be interfered, and has a certain interference effect. ...
