DCUP-Terrain contouring ALCM's

You seem to know alot about weaponry. If you knew the path of cruise missiles towards their targets; and you knew they were going to use terrain countoring system to check their course couldn't you put things on the ground below the flight path to fuck it up so the computer things it is NOT on the right course and makes a correction ie mistake in course?

im sure they'd have a back up GPS system in each missle as well

They have GPS. But they use a terrain countoring system aswell to check the course is correct with GPS. I got one; if you had a good radar system and new when cruise missiles were coming, couldn't you have basic EMP devices littering the ground and blow them up when missiles are above them? Like ground e-bombs.

intresting thought. im not sure if missles would get EMP shielding....

The TERCOM (Terain Contour Matching Guidance System) corrects itself along its flight plan! Using its radar it scans the ground that the missile is passing over! The data that is collected is then compared to digital maps that are stored in a computer in the nose of the missile! If the comparison on the TERCOM map grids shows that the missile has drifted off of its intended path, the inertial navigation system is reset and a course correction is made so that the missile gets back on course! This process is repeated at many locations along the flight path, so that the missile is never allowed to drift very far before its path is corrected!

But I guess hypothetically if the terrain was masked at the end of its flight, it could alter its course by 10-20 meters! If you could mask the terrain for hundreds of miles and cover all of the grids in the path you would alter the TERCOM flight path by Hundreds of meters or more! Jamming or destroying the TERCOM radar would be the most effective way of messing up and course it to drift of course! It could not correct its flight path!

The TERCOM guidance system is very important still with GPS because of enemies, malfunctions, and Solar storms could take out the GPS Satellites!
