Synchronization and performance of MANET-based obstacle detection systems

The paper describes possible scenarios and transceivers structures for providing synchronization in MANET-based distributed radar and communication systems. Two approaches were reviewed in terms of performance and synchronization requirements for omnidirectional antennas: beam forming technique and synthesized radar aperture. The calculations show that the synchronization requirements could be softened by distributed use of sensing signals with unique sequence for each node. Designed structure is optimized with regard to obstacle detection method with Voronoy diagrams optimization and using simplex codes for providing energetical concealment. The chosen method allows generation of the digital map with accuracy up to 5 m on the distance of 5 km.
