5.2.2 Parameter of BSD system
 For Y:
 If relative speed of object≦ Vy_dynamic_alarm_min then Y=
y_dynamic_alarm_min
 If relative speed of object≧Vy_dynamic_alarm_max then Y=
y_dynamic_alarm_max
 If Vy_dynamic_alarm_min <relative speed of object<
Vy_dynamic_alarm_max then Y is linear interpolation between
y_dynamic_alarm_min and y_dynamic_alarm_max.
