I am a final year electronics and communication student. I wish to do my main project on audio spotlight.But i don't know the implementation.
The audible sound is firstly converts into high frequency in audible one.It then focussing with a Hypersonic sound emitter in the desired direction.
It says ,it can be demodulated automatically while travelling due to the non linearity property of air.There is an expression relating the distance and demodulation.
Where can i get this? How can i practically implement this? Help me.. Give me some advise..
