Optimal algorithm of ultra-wideband signals processing in 3D mapping systems with two antenna arrays

The optimal algorithm of ultra-wideband signals processing in systems 3D mapping with two antenna arrays is synthesized. According to the algorithm of signals processing the block diagram of optimal radiometric system with antenna arrays is developed. The use of antenna arrays allows to increase the scanning speed and reduce the weight the system. An analytical expression is found for the limiting error of the coordinates estimation.
