Hi thanks for the reply.. can you do some derivation for the solution and tell me how to do it? actually it is an object tracking technique i want to develop...the point i have mentioned is, you can say a moving object, which has to be tracked by an observing unit at ground that has a detection range in the form of a cone. in order to be tracked, the object should be within the conical range of the observer unit. now i think the question is clear. just imagine that the observer unit is on ground and it can move to make a cone of height h and radius r to detect the presence of a target..help with 2D will also be appreciated.

hi,can you tell me how to determine the equation of cone? and we just have a point or target that will determine the line, so then we have to see if that line intersects the cone or not? i mean the problem is an interception problem where we want to see if the cone will intercept the line or not? hopefully this clears the question.
