摘要
介绍了一种机载多波段SAR接收/激励器及其实现。该子系统由VHF/UHF、L 、X和 Ku四个波段组成,采用了多波段融合、基于DDS的宽带波形产生、宽带正交解调接收和高频率稳定度抗振频率合成等技术。文中最后给出了实验结果。
A receiver and exciter for multi-band airborne SAR is introduced in this paper. The subsystem includes VHF/UHF, L, X and Ku bands, and adopts several advanced technologies such as multi-band fusion, DDS-based wide-band waveform generating, wide-band demodulator receiver and airborne low phase noise synthesizing. At last, the experiment results are provided.
