S-band time domain near field planar measurement for RCS inside an anechoic chamber

This article describes a time-domain near-field planar measurement system constructed in an anechoic chamber. Distinct from conventional radar cross section (RCS) frequency domain system, the time domain measurement system consists of time domain facilities can obtain RCS results in a wideband by a measurement. Meanwhile, a weighted window function method brought in the process of near-field to far-field extrapolation for error correction. Finally, the measurement results of experimental validation of the system are demonstrated.
