Abstract: The present invention provides an unmanned fully autonomous threat representative mobile land target for testing modern weapon systems and training personnel. The invention implements novel navigation and vehicle control algorithms which allow any predefined course to be represented spatially and temporally with continuously and smoothly varying curvatures having no discontinuities of curvature, direction, or acceleration that enable the target vehicle to traverse a predefined course with unprecedented speed, accuracy, and maneuverability without the need for communication with any remotely located station. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope of the claims.
