The present invention discloses a method and device for shielding data interaction through a microwave radar. The method includes the following steps that: the attribute of a target scene is judged through the microwave radar, the attributes of scenes are divided into a first attribute or a second attribute, data interaction is not allowed in a scene of the first attribute, and data interaction isallowed in a scene of the second attribute; if the attribute of the target scene is the first attribute, the microwave radar is controlled to enter a signal shielding mode; and after entering the signal shielding mode, the microwave radar transmits interfering radio waves to interfere with data interaction in the target scene, so as to not allow the data interaction to be performed in the targetscene. According to the prior art, a signal shielding device cannot identify a scene and cannot adjust the frequency of interference signals, and as a result, a signal shielding effect is poor, while,with the method and device of the intention adopted, the problem in the prior art can be solved, the attribute of the target scene can be identified, so that communication signals can be intelligently shielded.
Description
technical field [0001] The present application relates to the field of radar technology, in particular, to a method and device for shielding data interaction by microwave radar. Background technique [0002] In the prior art, the signal jammer transmits a fixed-frequency interference signal to shield the signal in the designated space, but it cannot judge the scene by itself according to the activity status of the personnel, nor can it judge that people use mobile phones to surf the Internet and communicate or use WIFI to communicate online in different locations. The number, and calculate the transmission power of different frequency bands of communication equipment through the mobile phone Internet access, and the antenna of the signal shielding device cannot be adjusted according to the location of the personnel, so as to change the frequency of interfering radio waves and achieve the purpose of intelligent shielding signals. [0003] Aiming at the above-mentioned problem...
