In this paper, some factors which caused the squint in the airborne dual-antenna interferometric SAR (InSAR) systems are firstly discussed. Then, the interferometric capability influenced by the squint is analyzed in brief. To eliminate such adverse effects, several measures are discussed and a novel processing approach is proposed. Using the inertial(More)
Generation of digital elevation models (DEM) from interferometric synthetic aperture radar (SAR) data is a well established technique [1]. But there are still some imperfections, such as multipath effect, in airborne interferometric SAR systems. The interferometric derivations assumes that a single path with the signal propagating from the transmit antenna,(More)
In this paper, a new hybrid general-purpose computation on GPU (GPGPU) and computer graphics synthetic aperture radar (SAR) simulation method for complex scenes is proposed. Previous SAR simulations for complex scenes only use GPU’s graphics capabilities for scattering calculation in graphical electromagnetic computing (GRECO) algorithm. The new hybrid(More)
