Summary:
Via sub-ns pulse source and sampling oscilloscope, synchronous acquisition of target scattering echo pulse is achieved by adopting the dual-receiving antenna. The target scattering stretch resulted from groud multi-path effect is avoided by adjusting the measurement height. Ultra-wideband (UWB) radar cross section (RCS) distribution of the target is obtained. Compared to the calibration targets’ theoretical RCS, the measured results’ average error is less than 1 dB, and the time-domain inverse synthetic aperture radar (ISAR) imaging demonstrate the effectiveness of our measurement system and the data processing method.
