Abstract: A method for determining an operational geographical zone relative to a sensor may include a step of simulating the position of said sensor; a step of determining a first zone of the region of interest; and a step of determining a second zone of the region of interest. The region of interest of the first zone may be constituted by points at each of which said object at that point traveling at a speed greater than or equal to said speed VT and in a given direction, would be seen by the sensor as having a radial speed greater than a threshold speed defined for that point. The operational geographical zone. may be defined by taking account of the intersection of the first zone and of a coverage zone of the sensor.

Abstract: The method serves to determine an operational geographical zone (ZO) relative to a sensor (S) configured to observe and measure the radial speed of an object traveling with a non-zero minimum speed “VT” in a region of interest (ROI). The method comprises: a step of simulating the position of said sensor (s); a step of determining a first zone (Al) of the region of interest constituted by points at each of which said object at that point traveling at a speed greater than or equal to said speed VT and in a given direction “DT”, would be seen by said sensor (S) as having a radial speed greater than a threshold speed defined for that point; and the operational geographical zone (ZO) being defined by taking account of the intersection of the first zone (Al) and of a coverage zone (A2) of the sensor.

Abstract: A determination method for determining at least one region of interest in at least one operational geographical zone. The operational geographical zone determined relative to a sensor to observe and measure the radial speed of an object traveling in a region of interest. The method may include steps simulating the position of the sensor in the region of interest at a determined position and orientation; determining at least one first zone of a region of interest; and determining a second zone of the region of interest, the second zone constituting a coverage zone of the sensor in which an object travelling in the region is observable while accounting for at least the position of the object relative to the sensor. One operational geographic zone is defined by taking account the intersection between the first and second zones.

Abstract: The method serves to determine an operational geographical zone (ZO) relative to a sensor (S) configured to observe and measure the radial speed of an object traveling with a non-zero minimum speed “VT” in a region of interest (ROI). The method comprises: a step of simulating the position of said sensor (S); a step of determining a first zone (A1) of the region of interest constituted by points at each of which said object at that point traveling at a speed greater than or equal to said speed VT and in a given direction “DT”, would be seen by said sensor (S) as having a radial speed greater than a threshold speed defined for that point; and the operational geographical zone (ZO) being defined by taking account of the intersection of the first zone (A1) and of a coverage zone (A2) of the sensor.
