摘要：
Based on the characteristics of the digital radio mondiale (DRM), a new method of array calibration for high-frequency passive radar (HFPBR) by using frequency reference signal of direct wave is proposed. Firstly the signal structure of DRM is introduced, while the feasibility of take frequency reference signal as the calibration source is demonstrated. Secondly, taking into account the electromagnetic environment and time-varying non-stationary propagation characteristics, a method of choosing high quality direct wave period by the shift-invariant antenna pairs is proposed. Finally, assist by the known DRM transmitter position, we utilized this method deal with measured direct wave data which propagate in surface wave mode and sky wave mode, compared the result of array calibration value with known single frequency signal source. The results showed that the amplitude and phase compensation method in DRM-based HFPBR is effective.
