Problems solved by technology

[0002] The radio jamming machine in the prior art has a single function, and can only interfere with signals of a certain specific frequency or frequency band, and cannot realize computer control, and cannot simultaneously perform multi-frequency, multi-bandwidth and diverse signals in the entire ultrashort wave range. Continuous or timed controllable interference in this way, and the equipment is heavy and can only be carried on the vehicle, but it is difficult to move and it is not convenient to use

Abstract

The invention relates to a computer-guided radio interference system, which is characterized in that the output terminal of a power amplifier (A) is respectively connected with the input terminals of a center-fed antenna and a cage antenna; the output terminal of a power amplifier (B) is connected with the input terminal of a discone antenna; the output terminal of an interference exciter is connected with the input terminals of the two power amplifiers; and the input terminal of the interference exciter is connected with a notebook computer and a panel. The computer-guided radio interference system has the advantages of computer guiding, high intelligence, graded setting, stable output power and selectable magnitude. The system has self-checking and automatic protection function on open circuit, short circuit, overheat and overvoltage. The system can also implement effective interference on conventional signals such as single-frequency signals, frequency-collecting signals, frequency-hopping signals and frequency-expansion signals, with the advantages of full intelligentization, wide frequency band, continuous tuning, high stability and adjustable transmission bandwidth. The system can set single-frequency, multi-frequency and wideband-stopping (optional bandwidth from 1 KHz to 20 MHz) interference transmission manners, and can set continuous transmission or timing transmission. The modulation signal can be selected from noise, electronic sound and external sound. The system can be powered by AC and DC and has convenient use.

Description

technical field [0001] The invention relates to a computer self-guided radio interference system, which belongs to the technical field of broadband radio interference. Background technique [0002] The radio jamming machine in the prior art has a single function, and can only interfere with signals of a certain specific frequency or frequency band, and cannot realize computer control, and cannot simultaneously perform multi-frequency, multi-bandwidth and diverse signals in the entire ultrashort wave range. Continuous or timed controllable interference in this way, and the equipment is heavy and can only be carried on the vehicle, but it is difficult to move and it is not very convenient to use. To this end, our company has concentrated years of advanced technology and experience in the fields of radio monitoring, signal detection and electronic countermeasures, and adopted the most advanced antenna technology, software radio and signal processing technology, and intelligent ...
