Tracking a radio signal

It's often possible to arrange for a very sharp "null" in the antenna pattern at the sides. Aiming for minimum signal can be a good strategy when trying to determine the direction to a transmitter.

This obviously does not work if you're simultaneously attempting to decode the signal, but an obvious workaround is to use one receiver with an omnidirectional antenna to read the data, and another receiver on the directional antenna to determine where the signal is coming from.



Is the signal format set in stone? A wideband "spread spectrum" transmission with a separate spreading code for each transmitter would be more immune to interference between transmitters.
