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.
