Sub-Nyquist SAR Based on Pseudo-Random Time-Space Modulation

Sub-Nyquist SAR Based on Pseudo-Random Time-Space Modulation

Sub-Nyquist sampling technology can ease the conflict between high resolution and wide swath in a synthetic aperture radar (SAR) system. However, the existing sub-Nyquist SAR imposes a constraint on the type of the observed scene and can only reconstruct the scene with small sparsity (i.e., number o...
