A Novel Quadrature Demodulation Based on Shifted Matched Filter in SAR Imaging Processing

摘要：

There is an increasing performance demand in receiving system of synthetic aperture radar (SAR) in recent days.Different kinds of digital quadrature demodulation (DQD) algorithms have come down to the filter design. A novel DQD filter based on the shifted matched filter is introduced in this paper. The performance of different filters is evaluated based on simulated echo data of one point target.Simulation shows that proposed filter can make the DQD meet precision demand and reduce computation greatly. The work in this paper provides a guide to design digital receiver in SAR.
