Patent ID: 7486229

Claim:
A terrestrial moving target accuracy test device, comprising: a detector deployed at a test location detects a plurality of terrestrial moving targets and generates a Ground Moving Target Indicator (GMTI) data input containing a plurality of ground moving target information; a Global Positioning System (GPS) device positioned at an objective target in proximity to said test location generates a GPS data input, said GPS data input further comprising a plurality of GPS objective target information; a means for GMTI data input, having a first means for data storage, receives said GMTI data input and converts said GMTI data input according to a NATO-EX standard; a means for confirmation verifies that said GMTI data input is correctly populated according to said NATO-EX standard; a means for GPS input, having a second means for data storage, receives and stores said GPS data input; a means for data conversion, having a plurality of conversion algorithms, converts said GMTI data input and said GPS data input into a common machine-readable format; a single pairing matrix assembly module combines said GMTI data input and said GPS data input into a matrix; a matrix error correction module compares said plurality of ground moving target information with said plurality of GPS objective target information that serves as a reference point; said matrix error correction module provides a matrix error correction input to a means for calculations; said calculations means identifies a group of variances between said plurality of ground moving target information and said plurality of GPS objective target information to determine a level of target detection accuracy; said level of target detection accuracy is converted into a graphical display for a user on a means for display; said graphical display includes a circular error of probability to identify the likelihood of detecting a discrete target at a location relevant to said test location at a given instance in time; and said graphical display indicates a plurality of detection accuracies of said device.
