Signal bandwidth and integration time are two significant parameters of a geosynchronous synthetic aperture radar (SAR) sensor. They directly determine the resolution characteristic of SAR imagery. Because their contributions to the ground impulse response width (IRW) curve (consists of -3-dB resolutions in every direction) are severely coupled, an(More)
GEOSAR has the characteristics of wide coverage and short revisit time. But when the GEOSAR is both used as a transmitter and a receiver, its advantages is not well exploited. If an airplane or a LEO satellite is replaced as a platform of the receiver, we can not only observe the interesting regions flexibly, but also achieve finer resolution. However, the(More)
