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.
