Personnel fire-finder...

[Seiyuuki]

I know there are specialize fire-finder radar use to track trajectory of mortor round and artillery to pinpoint their location. Is there any sort of fire-finder sensor in existence or in development for infrantry, where you can track trajectory of bullet to find hidden sniper, etc. giving the nature of urban warfare, it could be useful.

The Lawrence Livemore Laboratories developed a rifle mounted system awhile back called Lifeguard that can actually track a bullets path and chart its path back to the source.

In Britain the Army has actually been using a system CLARIBEl to detect snipers since the '70s, thanks to their involvment in Northern Ireland. It basically found snipers by detecting the muzzle blast but from what I read it wasn't a very good system.

A British company called GD Associates have developed a system for the Brit. Army called the Bullet Direction Indicator and it basically uses a system of sensors to detect the shockwave caused by a passing bullet. Afterwards it just triangulates the path back the source.

Theres probably some more programs but those are the ones I can think of for now.

It would be AMAZING to have technology like that, integrated with a HMD on infantry squad leaders etc., in the future. It would change everything when it comes to snipers, FIBUA etc.

Yes and it is in use currently.

Not being used, as far as I know is AAI's detection system, designed by my uncle. it uses four sets of crystals three mounted on the same plane with a fourth higher. The flight of the round, supersonic, cause the crystals to oscillate, which gives proximity, angle, and caliber type.

There are others that use sound location.

His original design was for a test bed anti-ordinance gun. The attempt was to shoot a main tank round out of the air with another. Sensors would detect the flight of a round the moment it left the barrel of the gun, analyze the flight trajectory, wind speed, heat, air density and temperature, etc etc and then launch another an intercept round.

I do not know if it ever worked or not.

Our friend Ralph Peters has been talking of "boomerang" systems for armour in urban combat lately, I'll see if I can dig it up.

Since I had some free time I figure I would do a little search to find some examples of this type of system(s)..

The first is Rafael

Same basic principle, sort of, as the AAI model I mentioned.
