Measurement in Time Domain for Ultra-wideband Electromagnetic Scattering Signals

In this paper, a system for measurement of ultra-wideband impulse scattering responses from scale model radar targets in time domain is described. The method of acquisition of the scattering signal, and signal processing technique for measurement data are also depicted in detail. Three scatterers, including a PEC sphere, a missile scale-model and a plane scale-model, are measured using this system. Compared the measured data with the numerical results, the result shows a good agree. It is indicated that the system can be used to measure and analyze uhra-wideband electromagnetic scattering characteristic for arbitrary shape targets.
