N2 - The extraction of a radio holography signal (RHS) is the precondition of shadow inverse synthetic aperture radar (SISAR) imaging. However, the target return usually has a relatively high carrier and narrow bandwidth when detecting ground moving targets, which makes it difficult to achieve the baseband signal with synchronous demodulation in a conventional Forward Scatter Radar (FSR) system. Thus a new method for RHS reconstruction is put forward in this paper. The method consists of envelope detection, segmental Hilbert transform and amplitude compensation. With these steps the target RHS can be accurately reconstructed and target profiles can be extracted via the SISAR algorithm. The effectiveness of this method is verified with both simulation and experimental data processing results.
