Abstract (en)

[origin: EP2687809A1] Missile guidance involving projection of laser light to define a Laser Information Field (LIF) is augmented by interposition of information pulses, interleaved between laser emissions establishing the LIF. Information pulses encode further information for receipt by a missile, such as an angle of roll of a missile launch platform from which the LIF is emitted.
