The result is an accelerating PN track with a superimposed sinusoidal weave.

These target trajectories are constructed from the target models defined in §2.2, and are activated by setting the value of TGT_SEL: • 1 User specified trajectory defined using only input data. • 2 Alternating periods of constant velocity and acceleration along X A applied to a crossing target. • 3 Same as (2) with an evasive turn 2 s before missile impact. • 4 Same as (2) with an evasive barrel roll 2 s before missile impact.
