In general, RCS measurement must meet the far-field condition, which need a vast measuring area or a costly compact range. To solve the problem, a new technique by extrapolation correction dealing with near-distance RCS measurement of aircraft targets is set up. The RCS of aircraft target under spherical wave illuminating can be adopted to extrapolate far-field RCS of them. The convolution arithmetic...
To meet the requirements of the outdoor radar target scattering measurement, a 2-channeI instrumentation radar based on pulse-to-pulse frequency shifting technique was designed and realized. The radar can perform radar-cross section (RCS) measurement simultaneously on two fixed frequency band, and test 2-dimension imaging cooperated with a rotation platform. The pulse-to-pulse frequency shifting technique...
