| Popis: | Algorithms based on the Wiener filter provide effective clutter cancellation in passive radar. However such algorithms are computationally intensive. Recently some Fourier-domain techniques have emerged for efficient clutter cancellation when the illuminator of opportunity uses OFDM modulation. By reinterpreting the Fourier method as an oblique projection of the surveillance return we show that it can be generalised to apply approximately to any modulation type. Efficacy of the method is demonstrated by application to simulated and real data. Refereed/Peer-reviewed |
