Abstract
In this work we present a novel method to do measurement correlation between
target observations made by two ormore radar systems. Some of the most common
radar sensors available are those measuring only range (distance to the target) and
bearing (azimuth angle). We use these measurements to determine the correlation
between two diĀ¤erent sensors observing the same target. As a by-product of the
correlation algorithm, we nd a way to estimate the target height for a target
observed by at least two radar sensors. The correlation method is expounded
upon, where we discuss measurement correlation for moving targets. Targets are
tracked using a Kalman Filter, and correlation is done between new observations
and existing target tracks. Finally, the correlation algorithm is implemented in
an interactive 3D computer simulation. Results obtained indicate a high success
rate, with false correlations only obtained where sensor accuracy is the limiting
factor.
