Title: What guidance should I use for my missile?
Minnysota - February 14, 2012 09:27 PM (GMT)
Some of you may remember a while ago when I designed the HK7 and the HK7A hypersonic cruise missiles. Well, I have decided to improve upon the write up since the current ones are not only vague, they flat out suck. I'm already getting help with the ramjet and related information, but I need help figuring out what type of radar/guidance I should use. I was originally planning on going with something where the missile could search for targets on its own, but I'm not sure of how far away that is in terms of tech. So would an active radar be good for use on a hypersonic cruise missile?
P.S., I'm far from smart when it comes to this stuff. Please, bear with me if I ask a lot of questions.

Stable-table Inertial package with TERCOM option and RADAR/IIR terminal guidance (to ID the target and strike a critical component*, pretty much TV guided with pre-defined silhouets with marked priorities in the case of AShMs)
*Such as their bridge, CIWS, (open) aircraft-elevatores/hatches, or radar-masts, while avoiding stuff that has already been hit and is still burning.
Because nothing sez "Ur so fucked" like a cruise-missile sailing right through the mess-hall at mach-5 right before slamming into the officer's quarters and radio-room; spilling unburnt rocket-fuel and shrapnel all over.
Informing it to target an individual officer, although possable, would be impractical and easy to exploit.

JASSM is IIRC fire-and-forget, or at least one of the missiles from that programme is. The technology is not outlandish and it is well possible that a few (if not a lot) existing cruise missiles search for targets on their own too.

Going by what Matt told me, there pretty much is no other option really. IR faces much clutter in heavy weather appearently.

Active radar is:
2. Your only real choice. Infrared is a no-go at those speeds. Well you could use an EO (television) seeker a cruise missile that only works during the day in good weather isn't such a great value. Especially at sea.

In which case means X-band radar or narrower in order to get enough resolution to recognize an open hatch-cover.
