Abstract:
A method for automatic association of moving target indications from at least one entity traveling along a known route, comprising:identifying a route within a detectable range of a moving target indicator radar; using the moving target indicator radar to detect a plurality of indication data of at least one moving target; selecting the moving target indication data proximate to the identified route; presenting the selected moving target indication data in a distance-time coordinate, such that each selected moving target indication data has a unique distance value and a unique time value; transforming the moving target indication data from the distance-time coordinate to a slope-distance intercept coordinate, such that co-linear moving target indication data in the distance-time coordinate are transformed into a plurality of points superposed together with a substantially identical slope value and a nearly identical distance intercept value; mapping the single point back to the distance-time coordinate; and associating the moving target indication data corresponding to the single point to a single entity.
