Abstract: A method for determining a threat against a border from objects crossing or trying to cross said border. Said method includes at least the steps of segmenting the border into border elements of uniform terrain features, infrastructure and weather conditions, collecting data of incidents occurring along a given border element, determining a threat potential for said border element, determining a protection factor for the border element, and determining a threat against the border element from the threat potential and protection factor. The method may be used for warning about an increased threat to a border, wherein the threat is compared with a threat value threshold. If the threat exceeds the threat value threshold, an alarm is issued. The method may also be used for allocating protective measures along a border.

Abstract: A method is disclosed for determining sensor performance of a border element of homogeneous terrain, weather and vegetation properties. The border element includes a number of areas of interest, as well as a plurality of sensors. The method includes determining coordinates of the border element and areas, and determining performance data for each sensor. The coordinates and performance data is used as input parameters to a Line-Of-Sight tool for determining a coverage factor of each sensor. The coverage factor is modified for time per time unit in which function of each sensor is impaired by conditions such as bad weather, light or mobility. Then, the modified coverage factors for each sensor are summed to obtain a total sensor performance for the border element.
