Abstract

The noise equivalent angle (NEA) is determined for a class of nose tracking algorithms that determine the leading edge by use of a partial body centroid algorithm. Analytical expressions for the track error and jitter variance are derived for silhouette and two types of intensity weighted centroid processing for a range of nose shapes determined by the parameter (alpha) . Graphical results are presented for triangular, parabolic and rectangle nose shapes. This paper only considers the effects of additive noise. Spatial quantization is not included.
