Multi-position MIMO Space SAR Principles and Signal Processing

The article proposes the concept of a multi-position space SAR. The proposed approach is designed to solve the problems and replace of large SAR based on AESA, to increase the reliability and replaceability of its parts. Each element of the system is a simple transceiver with low output power. A high value of energy is achieved due to the possibility of using medium-sized passive antennas. When sensing, orthogonal code signals are used to ensure the incoherence of the operation of the system parts. Signals are received using MIMO technology.
