Method and system for correcting radio signal

Abstract

The invention discloses a method and a system for correcting a radio signal, and relates to the technical field of radio signal monitoring, the method comprises the following steps: simultaneously collecting each group of communication signals generated by an emission source, establishing an emission source coordinate system, and correcting the radio signal according to a radio signal and a radar signal in each group of communication signals; according to the method, corresponding radio positioning coordinates and radar positioning coordinates are generated, and radio signals in a certain group of communication signals are corrected when the radio positioning coordinates and the radar positioning coordinates of the certain group of communication signals are deviated, so that radio signals which are emitted by an emission source and are not interfered with each other are obtained. And the interference signal is generated according to the corrected radio signal, so that the interference effect of the generated interference signal on the emission source can be greatly enhanced, and the success rate of interference on the emission source is improved.

technical field [0001] The invention relates to the technical field of radio signal monitoring, in particular to a method and system for correcting radio signals. Background technique [0002] Existing navigation equipment is usually equipped with radio technology detection devices, radar detection devices, etc. The main task is to detect unknown radar signals, radio communication signals, etc., and obtain information such as their technical parameters, communication content, and location. Electronic interference refers to the use of electronic equipment and equipment to fight against the electromagnetic spectrum to achieve the effect of radio wave disturbance.

Problems solved by technology

[0003] At present, the electronic detection equipment on the market can only analyze the wireless electromagnetic wave signal emitted by the other party to obtain intelligence information, and cannot generate interference signals corresponding to the channel and sequence according to the intelligence information of the other party to carry out electronic interference on the emission source, while electronic interference equipment can only It can intercept the opponent's intelligence information to generate jamming signals for electronic interference, but cannot conduct signal analysis on the wireless electromagnetic wave signal emitted by the opponent to obtain intelligence information

[0004] During the flight of the navigation equipment, the radar positioning signal and radio signal sent by the transmitting source in the receiving range, if there is only one transmitting source in the airspace, the received radio signal at this time is the original signal, through which the radar positioning signal and radio signal can be Lock the unique and accurate geographical coordinates of the emission source, and the interference signal generated by the navigation equipment based on the radio signal has high accuracy and strong interference. However, during the actual flight of the navigation equipment, there are multiple emission sources in the receiving range, and the emission source Interference between the radio signals has occurred and the original signal has changed, resulting in the radio signals received by the navigation equipment after mutual interference. It can be intuitively found that the coordinates of the emission source solved at this time are inconsistent with the coordinates of the emission source positioned by the radar. The interference signal generated by the direct processing of the scrambled radio signal also has the problems of low accuracy and weak interference
