Complex electromagnetic environment dynamic generation method based on signal samples and modulation parameters

Abstract

The invention discloses a complex electromagnetic environment dynamic generation method based on signal samples and modulation parameters, and the method achieves the generation of an electromagneticenvironment based on a digital intermediate frequency signal processing method in a conventional electromagnetic environment generation method. The upper computer issues modulation parameters to the FPAG; the FPGA digital card processes the signals according to the modulation parameters and then outputs the signals; many kinds of modulation, the development difficulty of a modulation program on the FPGA is high; in the prior art, the new service function requirement is high, the realization is difficult, the service expandability is poor, and the upgrading is difficult, such that the complexity is high if the new development needs to be performed, the cost is limited, the expansibility is limited, the requirement on the operation mode of the user is harsh, and the upgrading and updating ofthe product are not easily performed. Based on this, the existing method is improved by designing the file of the application, and the conditions of high FPGA development complexity and poor expandability in the prior art are improved by the method.
