| The present paper is designed for the sake of developing a general testing system for radar anti-interference and thus satisfied the needs to conduct radar-modeling experiments on navy base. The system can simulate various kinds of targets, jammings, noises, clutters and other signals and thus adapt to all types of radar in terms of signal simulation. In this sense, the system is expected to provide the user with the most advanced simulation technology to do radar-modeling experiment in China.In the first Chapter, the paper presents an overview on the significance to research in the area of radio frequency simulation and a literature review on radar technology developments at home and aboard. Then it discusses the feasibility to conduct research in radio frequency simulation technology. The following Chapters introduce an undergoing research system on technological parameter, system working mechanism, structure composition and module functions.The paper elaborates on the simulation principles and ways to simulate radar targets, jammers and clutters, etc. Based on the related mathematics model, the paper focuses on the further exploration on DRFM, DDS, digital noises emergence and how to simulate clutters by combining software and hardware as well. |
