- W2793516142 abstract "This study examines the problem of solving the Doppler ambiguity in analogue television (ATV)-based passive bistatic radar. When mismatched filtering is used to deal with the range ambiguity at 19.2 km, the Doppler ambiguity caused by the 50 Hz field frequency is equally rising because of the signal-to-noise ratio (SNR) loss in the main lobe. Aiming at this problem, an improved mismatched filtering algorithm is proposed. In this new algorithm, the Doppler ambiguity sidelobe suppressing is considered into the cost function, and the mismatched filtering factor is acquired based on minimising the SNR loss, the range sidelobes energy and the Doppler sidelobes energy. Moreover, a batch version is applied to lower the computation. Then the performance of the improved mismatched filtering algorithm is verified by the theoretical analysis. Finally, the application of real data proved the effectiveness of the improved algorithm." @default.
