Doppler radar for high speed small objects

Dave Mepham
Prodigy 10 points

Hi

I am trying to build a doppler radar to measure the speed of bullets fired out of a gun. The radar unit will be located next to the gun and will measure the velocity of the projectile as it moves directly away from the muzzle of the gun. The radar should be able to detect objects travelling at up to 4000fps and be about 5mm in diameter. Does TI have any radar components that could form the basis of this project?

Thanks

    Hello.

    This application is not something that is a common use case for mmWave radar.  The velocity is very high and cannot be processed by our out of box processing chain.  Please refer to this e2e for further information as to why it isn't supported and what potential steps you can make to possibly support this application.

    Sincerely,

    Santosh

    Dave - 

    I shoot competition target air pistol (4.5mm / .177) and also .22 cal and of course have thought of same usage versus using microphones or optical in the target (I own a microphone based e-target) - The typical speed for air pistol pellet is around 500fps (340mph) and standard velocity for .22 cal pistol is around 1040 or 1070fps. Is this same application use case? (electronic scoring target or chronograph RADAR, like the LabRadar box, for example)  - is your requirement really 4000fps??? (that is >2700mph - I have not seen any guns that run that hot)
