An embodiment of the invention provides an interference signal generation device, an interference signal generation method and interference signal source equipment. According to the interference signal generation device, the interference signal generation method and the interference signal source equipment, modulation signals corresponding to a plurality of interference frequency bands can be calculated according to signal interference requirements of a target environment, each modulation signal is utilized to generate a plurality of interference signals for the target environment, and the plurality of interference signals are superposed and then transmitted; and the interference signals meeting interference requirements are flexibly generated, full-band interference is not needed, and therefore the number of parts such as antennas can be reduced, the size and power consumption of interference signal source equipment are reduced, and vehicle-mounted environment requirements are met.
Description
technical field [0001] The embodiments of the present application relate to the technical field of signal interference, and in particular, to an interference signal generation device and method, and an interference signal source device. Background technique [0002] In many occasions, for information security, property safety, personal safety and other safety protection purposes, it is necessary to interfere with the communication in the target area. The interference signal is sent to the target area by the interference signal source device to achieve the purpose of interfering with the communication signal in the target area. [0003] In the existing implementation, the frequency band covered by the interference signal source device and the modulation method adopted are fixed in the device hardware. Therefore, some interference signal source devices use power suppression to interfere with signals in all frequency bands, resulting in high transmission power and large equipm...
