Coherent Multistatic UAV-Based SAR [PDF]

IEEE Transactions on Radar Systems
Multistatic synthetic aperture radar (SAR) with uncrewed aerial vehicles (UAVs) as platforms enables applications not possible with monostatic SAR by spatially separating transmitter and receiver. Single-pass interferometry and tomography or the analysis of different scattering mechanisms becomes feasible while having the large flexibility of UAV-based
