A Novel Algorithm for Spacebome SAR DBF Based on Sparse Spatial Spectrum Estimation
2018 China International SAR Symposium (CISS)(2018)
摘要
A novel method of digital beam forming (DBF) based on sparse spatial spectrum estimation for spaceborne synthetic aperture radar (SAR) is proposed in this paper. This method converts the estimation of target scene elevation into the estimation of sparse spatial spectrum., which reduces the impact of the number of signal samples. Finally., the simulated results confirm the validity of the method.
