“…In an experiment to evaluate the ground-penetrating performance of the TDBP algorithm for a designed UWB radar system with multiple transmissions, the system uses a Vivaldi antenna and a vector network analyzer (P2023B) with an iron skin made of conductive material as the target [11] . The target is placed in a 100 cm x 60 cm x 80 cm (L*W*H) sandbox and a simple method is used to estimate the dielectric constant of the sand.…”

“…All the received signals are used to reconstruct SAR images based on different kinds of algorithms. The back-projection algorithm is the most common algorithm [ 5 , 27 , 28 ]. To construct an antenna array with a low side lobe level, the distance between the array elements should be less than half the wavelength, which is practically impossible in most cases.…”

“…The offset of target echo in the Doppler frequency domain can also play an important role in multiple input multiple output (MIMO) radar SAR imaging. In [ 1 ], high-resolution imaging is achieved by adopting the Doppler-division multiplexing (DDM) technique for MIMO channel separation and combining it with a single-channel BP algorithm and multi-channel synthesis.…”
