For the drawbacks of the synthetic bandwidth method based on time-domain back projection, a novel synthetic bandwidth method based on frequency-domain back projection is proposed in this article for stepped-frequency synthetic aperture radar to improve the computation efficiency and to realize the automatic spatial spectra cutting. To give a direct and clear comprehension for wideband synthesizing...
The initial altitude error (IAE) of high-speed diving vehicle can be as large as several kilometers, which results in serious defocus, position shift and geometry distortion for synthetic aperture radar image. In this paper, a novel IAE estimation method based on the principle of autofocus is proposed. The genetic algorithm (GA) is applied to solve the optimization model with advantages of global...
An innovative interferometry configuration, imaging and digital elevation mode (DEM) generation method via bistatic forward-looking synthetic aperture radar (BiFLInSAR) is addressed in this paper. The analytical relationship expressions between the interferometric phase and the topographic height are derived. In addition, for the space-variant features of BiFLSAR resolution and interferogram, an imaging...
For synthetic aperture radar (SAR), motion errors should be compensated to get well focused microwave images. The inertial measurement unit (IMU) is widely applied to compensate motion errors for back projection (BP) algorithm. However, the measurement errors degrade the performance of BP as well. Recently, an effective autofocus BP (ABP) algorithm has been proposed, but it ignores the spatial variance...
