Thank you all for replies.
If i can do I wanna measure the range with microphones like that. Artillery sound ranging - Wikipedia
If i can , I want to distinguish which type of weapon had fired.
If I can't do that, I want to locate gunshots to 2000 meters ( which type of weapon is not important ). Location will be with multilateration Trilateration - Wikipedia.
Any suggestion about hardware and idea?
Thank you.
