The system comprises n signal vector generators, a high speed collector, a down converter, a radio frequency front end multichannel microwave switch, m antennas and a microwave darkroom. The invention provides a semi-physical verification method of a custom ARB waveform mode to verify the anti-interference method of complex signals, which not only solves the problem that an instrument can not send the complex signals, but also can achieve accurate verification. In the verification, a curve of the semi-physical verification method and the curve of digital simulationare compared under different interference conditions, under different interference conditions, the curve of the semi-physical verification method and the curve of digital simulation have high consistency, which proves the correctness of the digital simulation and the validity of the semi-physical verification method. B adoption of the method, a certain theoretical support and a new idea are provided for the verification field of an unmanned aerial vehicle data link system on the basis of low cost, various interference conditions of the unmanned aerial vehicle data link can be simulated more quickly and effectively, and the anti-interference performance of the unmanned aerial vehicle data link is simulated and verified more sufficiently.

Description

technical field [0001] The invention relates to a semi-physical platform verification method for anti-jamming of a data link of an unmanned aerial vehicle. At this stage, due to the limitations of the instrument itself, it is impossible to generate such a complex signal. In order to verify the correctness of the algorithm, the ARB mode is used to generate a custom ARB waveform file. The hardware-in-the-loop verification system for complex signals is universal. The results show that the results of the method are consistent with the digital simulation, which proves the feasibility of the hardware-in-the-loop verification platform. [0002] technical background [0003] At present, for the UAV data link system, the full physical verification system is not easy to realize, while the semi-physical verification system has the advantages of simplicity and convenience, high practicability, low cost, and good accuracy, and is widely used in the UAV data link verification system. com...
