Abstract:
1. A method for establishing a scanning horizon for a radar installation at a first position, comprising the steps of: a) dividing the terrain surrounding said first position into a number of sectors, b) finding altitudes of successive points along a sector by consulting terrain information stored in a database, including near to the radar site, finding the altitudes in points along a line going outward from the site, and whenever the distance between an edge of the sector and the nearest point grows above a predefined distance, increasing the number of calculation branches by one, comparing the found values in parallel points, and choosing the highest value as the value representing this particular range, c) calulating an elevation value in each of the successive points along said sector from the relationship d) comparing the elevations of all the successive points in the sector to find a point of highest elevation e) storing said point of highest elevation for said sector in a front view terrain profile f) repeating steps b) to e) for another sector.
