Air Borne Ultra Sound Transducer

I am working on a security product who detect Intruders in a 10 meters range. I am asking Which manufactur can you recommend that builds Air Borne Ultra Sound Transducers as well if you know where can I find Electronic Circuits to implement a Low Distance (about 10 meters) ultra sonic radar.

Thanks in advance,

Vladimir

: ...Which manufactur... builds Air Borne Ultra Sound Transducers ...
You can find US tranducers for air any semiconductors catalog: RS, Farnell, ... Schukat, ELFA, I just named what I have at my hand. Manufacturers? Just take documents you have at their www sites. Airmar, S.Square enterprise Company just to name few. But bear in mind - these will be small size (10 to 40 mm) ~40kHz transducers.

:....where can I find Electronic Circuits to implement a Low Distance (about 10 meters) ultra sonic radar.

Same as above - go to US transducers manufacturers sites - here you will fing a lot of schematics, some of them are even included in documentation which is available on distributors mentioned above sites.
I doubt whether 10 meters with transducers you are probably thinking of, will be low distance. Especially if you are thinking of motion detection. Even with long/continuous signals it is complicated to obtain a reasonable measurements. If you are speaking about interruptible beam(through - transmission) then it is a little bit easier.Unless you use advanced signal processing or/and advanced transducers.
