Looking for an Ultrasonic Transmitter and Receiver

Hello,

I am currently looking for an ultrasonic transmitter and receiver that can be placed on multiple, separate robots. Every robot should have one transmitter and multiple receivers. The transmitter should be capable of sending a signal in every direction which a receiver on another robot would be capable of receiving.

The goal of this project is to create swarm robots, capable of communicating distance and orientations of other robots with respect to itself.

If possible, the both the transmitter and receiver should come with a board that has amplification and filtering capabilities.

Thank you
