Figure 15-5 : Missile – Target Relative Frames of Reference
The Missile Rolled frame (R) is located at point (m) and is subject to a roll
rotation about X B such that Z R points along the total lateral acceleration
demand vector.
15.14 Target LOS Frame
The Target LOS frame (T) shown in Figure 15-6 is located at point (o). X T
is a vector from (o) through the target at point (t). Z T points upwards and is
normal to the plane spanned by X T and Z A . Y T remains parallel to the plane
spanned by X A and Y A .
15.15 Target Body Frame
The Target Body frame (TB) shown in Figure 15-6 is located at point (t).
X TB points forward along the target’s longitudinal centreline, Y TB right and
Z TB down when the target flies straight and level. Although the target is
