Point Spread Function Analysis for GNSS-Based Multistatic SAR [PDF]
IEEE Geoscience and Remote Sensing Letters, 2015 This letter presents an analysis of the multistatic point-spread function (MPSF) for passive synthetic aperture radar (SAR) with navigation satellites as opportunity transmitters and a stationary receiver. It is shown that a noncoherent combination of bistatic SAR images, obtained by multiple, spatially separated satellites, can yield multistatic ...

Impact of oscillator noise in bistatic and multistatic SAR [PDF]
Proceedings. 2005 IEEE International Geoscience and Remote Sensing Symposium, 2005. IGARSS '05., 2005 This paper addresses the impact of limited oscillator stability in bi- and multistatic SAR. Oscillator noise deserves special attention in distributed SAR systems, since there is no cancellation of low frequency phase errors as in a monostatic SAR, where the same oscillator signal is used for modulation and demodulation.
