The digital processing aspect of modern traditional radar interference simulators uses narrowband architecture for digital channel transmission or parallel bandwidth architecture for high-frequency digital memory(DRFM).radar signal between channels changes frequency.The parallel DRFM broadband architecture is resource-intensive and makes it difficult to obtain multiple-way interference.This article focuses on radar interference simulation systems.In research and implementation,we have proposed a system architecture that combines narrowband architecture based on digital channel division and DRFM parallel bandwidth architecture to implement high-probability radar signal interference and simulation of monitoring targets bandwidth.The main content of this article is as follows.First,we analyze key technologies for radar interference and target modeling.Three typical patterns of active radar interference are investigated using simulation results and implementation methods,point modeling theory,and theoretical analysis of application methods.Design the architecture of the radar interference simulator system.The radar interference simulation system is divided into three subsystems: radar detection,narrowchannel architecture based on digital channels,and parallel broadband architecture based on DRFM.The structure of the frame is obtained as follows.Based on this,we propose a system architecture for a radar interference simulation system based on narrowband and parallel broadband DRFM architecture for digital channel separation.Second,it explores the main technologies of digital drainage and digital beheading.It combines prototype and multilevel structures for digital conductor and digital conductor to evaluate effective implementation structures for digital conductor and digital conductor and performs functional simulations using platform simulation.Next,we will look at the principle of the time domain energy determination method for channel detection and explain the detection algorithm.Verification of the design and simulation process for the specified signal protection and shielding functions.Next,let's take a look at the main high-speed parallel DRFM technologies.Analyze key technical indicators,get acquainted with the main structure and the principle of operation.The analysis is performed in two aspects: how to read and write DRFM memory and the parallel modulation of a broadband signal.In this article,we propose an effective Hilbert parallel filter to solve the real signal frequency change problem.Design an original Hilbert filter and combine it with a finite length parallel thrust(FIR)filter to achieve a parallel and efficient implementation structure.Functional simulation is performed and the consumption of material resources is explained.This was confirmed by the design platform(Vivado).Finally,the radar interference simulation system was tested.Brief description of the radar interference simulator hardware and software platform.The system test is divided into narrowband architecture for digital channel assignment and parallel bandwidth architecture for DRFM.The test results are analyzed to verify the accuracy of the radar interference simulator system architecture.The Radar Clutter Simulator developed in this document can be used as a reference in the design of the Radar Clutter Simulator system to validate the expediency of the application framework discussed by the author in actual tests and applications.
