| 摘 要： | 针对高频窄带系统的常规雷达辐射校准技术不能适用于低频超宽带雷达系统。根据低频超宽带雷达系统特点,采用矩量法和渐进波形估计技术,建立定标体的低频宽带散射模型,给出辐射校准函数,实现对UWBR的辐射校准。最后结合低频UWB合成孔径雷达系统,进行计算机仿真试验,证明这种方法的有效性。

| Abstract: | Regular radiometric calibration techniques developed for high frequency narrow band radar system are not applicable for low frequency ultra-wideband radar (UWBR). The low frequency scattering model is calculated using method of moment (MOM) and asymptotic waveform evaluation (AWE) technique, and the calibration method is proposed. Computer simulation is used to verify the validity of this calibration method. |
