Abstract: According to an embodiment of the disclosure, a computer implemented method of configuring a land-based radar system for scanning a scan region is disclosed. The method comprises dividing the scan region into a grid of blocks and obtaining a terrain elevation data for the scan region. For an elevation angle for the radar system, determining those blocks in the grid that are visible to the radar system and those blocks that are not visible to the radar based on the terrain elevation data. Then, step of determining the visible blocks is repeated for all elevation angles in a predefined set of elevation angles for the radar system. Next, an optimal scan elevation angle for the radar system is determined as the scan elevation angle which resulted in the maximum number of visible blocks in the scan region and the radar system is set to the optimal scan elevation angle.

Abstract: A communication system includes a data concentrator computer, a gateway device for communicating with the data concentrator computer, a first mobile data acquisition device communicating with the gateway device, and a second mobile data acquisition device communicating with the gateway device. The gateway device allows direct communication between the first and second mobile data acquisition devices without communication with the data concentrator computer.
