Research And Design Of Radar And Electronic Warfare System Simulation

With the continuous development of information technology,software-based radar technology has become increasingly mature.In order to meet the needs of radar and electronic warfare interaction,a digital prototype platform was built.The digital prototype platform uses computer software simulation to jointly and interactively operate digital prototypes such as radar and electronic warfare in a digital virtual environment,avoiding the loss of time and resources caused by the development and production of real equipment,and the construction of interactive environments.Design efficiency,shorten the development cycle,and ensure the reliability and maintainability of the system.System simulation refers to the simulation interaction process of radar prototypes,electronic warfare prototypes,environmental clutter and targets.It has the characteristics of complex interaction process,poor human-computer interaction,difficulty in unifying interaction timing,and large amount of digital signal data.Therefore,the design of the system simulation scheme is the key and difficult point of the digital prototype platform.The thesis focuses on the system simulation scheme,and the main results are as follows:The paper analyzes the function of the simulation environment and the design requirements of the simulation scheme,and designs the overall architecture of the system simulation based on HLA,which makes the complex interaction process simple.The solution is based on an open application system architecture and adopts an object-oriented design method to divide each interactive part into different federated members.The members have high internal cohesion and low coupling between members,which clearly realizes the complex interaction process.The paper designs a data interaction scheme based on data flow driving,and adopts a communication mode based on DDS subscription and publishing,which solves the problems of difficulty in unifying timing and poor human-computer interaction under a large amount of data in the interaction process.The specific plan is to define the two parties of the message delivery as the publisher and the subscriber.The subscriber subscribes to the publisher’s data,and the publisher transmits the data to the subscriber.This ensures the data transmission in the complex interaction process.The communication rate of the designed communication scheme can be Reach 40M/s,meeting the minimum communication requirement of 26M/s.Since each component is independent of each other during the data transmission process,it is sufficient to subscribe to the data display using an independent waveform display module,which greatly improves the human-computer interaction in the simulation process.A unified timing control module is designed,and timers are used in the signal generation part and the data processing part to solve the problem of inconsistent timing in the interaction process.The paper implements a digital prototype platform.The main modules of the platform include radar digital prototype,electronic warfare digital prototype,target digital prototype,communication module and integrated display and control module,which supports system simulation of the interactive process of radar and electronic warfare.The system simulation scheme proposed in this paper solves the difficulties of complex interaction process,poor human-computer interaction,and difficulty in unifying the interaction sequence during the simulation process of digital prototype.It has realized the rapid simulation of the working environment of radar and electronic warfare,and quickly carried out the algorithm function verification and performance optimization of the radar digital prototype and electronic warfare digital prototype,which greatly accelerated the upgrading of radar and electronic warfare equipment,which is of great significance to the national defense industry.
