Abstract
A method of distinguishing, from a moving platform, stationary objects from moving objects. The method includes using a first detector mounted to the moving platform to obtain at least a first reading from a target area, advancing the moving platform relative to the target area and using a second detector mounted to said moving platform to obtain at least a second reading from said target area. Then, the method includes comparing said first and second readings for at least two different time intervals to distinguish moving objects from stationary objects.
Claims7
A method of distinguishing, from a moving platform, stationary objects from moving objects, the method comprising:
- using a first detector mounted to said moving platform to obtain at least a first output representative of a target area;
- advancing the moving platform relative to the target area;
- using a second detector mounted to said moving platform to obtain at least a second output representative of said target area;
- determining an expected time delay between when said at least first output representative of said target area is obtained and when said at least second output representative of said target area is obtained;
- and
- making at least two comparisons of said first and second outputs for said target area at least two different time intervals, to distinguish, in said target area, stationary objects from moving objects.
A method of distinguishing, from a moving platform, stationary objects from moving objects, the method comprising:
- using a first detector mounted to said moving platform to obtain at least a first output representative of a target area;
- using a second detector mounted to said moving platform to obtain at least a second output representative of said target area after an elapsed time of TE;
- and
- determining an expected time delay between when said at least first output representative of said target area is obtained and when said at least second output representative of said target area is obtained;
- making at least two comparisons of said first and second outputs, one comparison at T<E and the other comparison at T>E to distinguish moving objects from stationary objects in said target area.
