这封信证明了利用伽利略导航卫星作为机会发射机来提高无源合成孔径雷达距离分辨率的可行性。这可以通过伽利略 E5a 和 E5b 信号的适当相干组合来完成。所提出的方法是通过分析得出的，并通过模拟和实验得到证实。
This letter demonstrates the feasibility of improving range resolution in passive synthetic aperture radar with the Galileo navigation satellites as transmitters of opportunity. This can be done by an appropriate coherent combination of the Galileo E5a and E5b signals. The proposed approach is analytically derived and is confirmed both by simulation and experiments.
