Description

Technical field [0001] The invention belongs to the field of radar digital interference, and in particular relates to a method for generating radar digital interference based on System Generator, which can be used for rapid simulation and realization of radar interference systems. Background technique [0002] In the design, simulation and implementation of radar jamming systems, how to quickly generate jamming signals and modify jamming parameters are important engineering issues in jammer design. Traditional digital jamming systems often use large-scale integrated circuits for digital signal processing to adapt to the complex environment of broadband, multi-modulation and multi-signal interference systems. There have been some research results using System Generator for system and algorithm simulation and implementation.

AI Technical Summary

Problems solved by technology

This method tries to use Simulink to construct typical suppression interference patterns, which can better reflect the dynamic change process of interference signals compared with other simulation tools. However, this method still has the disadvantage that it contains fewer interference patterns and only Capable of functional simulation and cannot be directly converted into hardware circuits

Although the modular design method of this method ensures the functional requirements of the platform design and builds a smart jamming platform, the shortcomings of this method are that the jamming pattern is single, the jamming module is not reusable, and other jamming styles need to be supplemented.
