There is still much secrecy about these types of artillery weapons. But small details can be found in publications.
I would say that several types of seeker heads are used on artillery rounds.
Infra-Red (laser designated option)
Anti-Radiation (like a HARM)
Optical (TV image)
And perhaps one other that I won't mention.
Or any combination of the above.
And in roughly the order they were invented.
I remember when the optical seeker came about. It was envisioned to be used as a basic TV picture, to show what was at the impact site. Transmitting
back to the artillery unit, they would be able to see where the targets were located.
The concept when millimeter wave seekers came about, was that any big chunk of metal, would be unable to hide from a targeting device of this type.
The seeker homes in on the attenuation of the metal. All metal reflects the radiation that is always in the environment. That reflection can be seen.
The joke at the time, was that you could bury your tank under 10 or 20 feet of dirt, and it would still find it.
Anti-Radiation, of course, homes in on any radios or radars that are transmitting. The Soviets were one of the first with this type of seeker in
GPS is one of the newest, and has good accuracy.
Imagine the first shot, with a camera, that identifies the targets down range, and transmits that information back to the command center. With modern
computers and software, a techie type could quickly designate which targets and which types of artillery rounds to send. Aided by the software, he
would send selected seekers at matching targets.
The use of RPV's for intel and recon in the battlezone, tends to eliminate the need for the optics. But it's possibly still an item that might be
used, as required.
The US Navy's intended use of 155mm AGS (Advanced Gun System) on the new DDX, gives an idea of what is possible. Able to out perform the 16 inchers
of the old battleships, in range, rate of fire, and accuracy. Capable of firing 10-12 rounds per minute of precision guided munitions. Combined with
the modern seeker heads and warheads developed. Intentions are to incorporate the US Army's 155mm XM-982 projectiles and the DTRA 5in projectile.
