A Real-time Control System About Radar Simulator Based On RTX

Radar echo simulator can generate radar echo signal with the methods of hardware and software combination. Radar systems can detect the target location and tracking performance, and thus can effectively shorten the development cycle of the radar system to improve efficiency and save a lot of cost.Radar echo simulator is an indispensable semi-physical simulation means in radar systems.Radar echo simulator based RTX real-time control system is to generate the target and background sea echo signal in a laboratory environment for radar seeker static performance evaluation, dynamic performance and anti-interference performance background.Firstly, this paper describes the basic system components and the system works, including system model such an objectives, jamming and clutter and implementation method.Secondly, the article introduces the real time defects of Windows operating system, and then introduces the windows real time extension subsystem RTX. This paper describes the basic working principle of RTX real time subsystem, and then the real-time network scheme is put forward and the optical fiber reflective memory card is introduced, including the theory of operation and the basic working principle. This paper describes the computer control software work flow simulation model, including local and remote control mode of the system simulation method of radar echo simulator, parameters of each simulation function are described, the important function module in the system software is analyzed.Finally, the system real-time and bit error rate is test. A detailed analysis of test is analyzed. And this paper points out the inadequacies of radar echo simulator real-time control systems that exist in this study. Then, a summary is made on the article and it points out the research direction in the future.
