Dynamic Generation Method of Complex Electromagnetic Environment Based on Signal Samples and Modulation Parameters

Abstract

The invention discloses a method for dynamically generating a complex electromagnetic environment based on signal samples and modulation parameters. In the existing electromagnetic environment generation methods, the electromagnetic environment is generated based on a digital intermediate frequency signal processing method; the host computer sends modulation parameters to the FPAG, the FPGA digital card processes the signal according to the modulation parameters and then outputs it. Due to the many types of modulation and the difficulty in developing the modulation program on the FPGA, the requirements for new business functions are high, it is difficult to implement, the business scalability is poor, and the upgrade is difficult. As a result, if new development is required, its complexity will be very high, and its scalability will be limited due to cost constraints. The requirements for users' operation methods are relatively strict, which is not conducive to product upgrades and updates. Based on this, the present application document is designed to improve the existing method, and the method improves the FPGA development complexity and poor scalability in the prior art.
