Abstract:

In view of the shortcomings of traditional electronic jammers, such as complex system, large volume and high power consumption, a kind of RF communication jammer using FXI specification is designed. Based on the definition of FMC signal, FXI specification defines the structure of FXI module and the exclusive signal group of FXI interface for the application of virtual instrument field, which improves the function density of virtual instrument module, to meet the design purpose of modularization, miniaturization and lightweight. A spectrum analyzer module and a RF signal generator module are simultaneously integrated into this jammer. The hardware logic is used to implement the real-time tracking of RF signals and the real-time synthesis of interference signals, so as to interfere the high-speed frequency hopping signals. With different modules for shortwave communication, VHF communication and microwave communication, the jammer could be used to different scenarios. After testing, the parameters of the jammer meets the practical using requirements. It can be further promoted to electronic countermeasures, UAV jamming and other technical fields.
