Abstract
A Guided Soft Target System is disclosed that includes a subject vehicle and a dynamic motion element (DME). The subject vehicle may be accelerated at an arbitrary rate to a speed corresponding to the speed in its own predetermined trajectory. Each of the DME vehicles computes its target speed as a ratio of the subject vehicle's speed at each waypoint location, and modulates its speed control to achieve this target speed. To further compensate for timing differences along the target path, each DME computes its longitudinal error along the path relative to its target position, as dictated by the position of the subject vehicle within its own trajectory, and each DME's target speed is modulated in order to minimize the longitudinal error along the predetermined trajectory.
