Description

technical field [0001] The invention belongs to the field of radar digital jamming, in particular to a method for generating radar digital jamming based on a System Generator, which can be used for fast simulation and realization of a radar jamming system. Background technique [0002] In the process of designing, simulating and implementing radar jamming system, how to quickly generate jamming signal and modify jamming parameters is an important engineering problem in jammer design. Traditional digital jamming systems mostly use large-scale integrated circuits for digital signal processing to adapt to the complex environment of broadband, multi-modulation, and multi-signal where the jamming system is located. There have been some research results in system and algorithm simulation and implementation using System Generator.

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.
