It can be done with an RF system using SAR techniques, if the vehicle has a precision INS installed. Fuse that with data from other sensors, and you can build

It can be done with an RF system using SAR techniques, if the vehicle has a precision INS installed. Fuse that with data from other sensors, and you can build a pretty good topo map of the road ahead of the vehicle.

I genuinely don't know all three acronyms you used there. Be honest. Do you think that most of the people that are browsing over and reading these comments are knowledgeable enough in your niche field to know all those acronyms? Probably not.

    Probably Synthetic Aperature Radar - http://en.wikipedia.org/wiki/Synthetic_aperture_radar http://en.wikipedia.org/wiki/Synthetic_aperture_radar RF is probably radio frequency INS is probably inertial navigation system - http://en.wikipedia.org/wiki/Inertial_navigation_system http://en.wikipedia.org/wiki/Inertial_navigation_system

  Which three? I only see SAR and INS, which I also don't know.

    "RF" was the third one. And I suppose I could take a guess and say it means "Radio Frequency". But just because the acronym's letters fit the phrase, doesn't mean I'm right as I am not knowledgeable in the field being discussed.

  SAR -> Synthetic Aperture Radar INS -> Inertial Navigation System RF -> Radio Frequency Yes, I should have spelled out the first two. The third I do expect most people here to know, given the context of the thread. > Do you think that most of the people that are browsing over and reading these comments are knowledgeable enough in your niche field to know all those acronyms? RF and sensors may be a portion of electrical engineering that is rarely discussed here, but it is hardly "niche". I made a quick post where I should have made a more detailed one. Mea culpa.

Are there any inertial navigation systems that work at all in ground vehicles? I'd expect otherwise due to e.g. vibration.
