Research on RCS measurement under non-far field condition

While stealth technologies for large scale targets were researched, RCS static measurement method was adopted, which is often used under non-far field condition. Therefore a theoretical premise was deduced, and a stepped frequency pulse compression system was designed for RCS measurement, especially a novel RF channel was designed to keep the system stable. Not only the simulation but also the experimental result is presented LU the paper; at the same time, some practical difficulties are designated.
