As in, radio interference from helicopters?

Well, the intention is a last-resort defense. There have been hundreds of videos where soldiers on the ground see drones way in advance. (Not kamikaze drones, but recon/grenade droppers.) You open box, point mini-drone in the general direction of the bad drone that is tracking you and press a button. The time window would be very short.

In theory, only a small antenna pair on the mini-drone is needed to approximate the position of a Mavic if it’s already pointed in that direction. I think even an ESP32 might be able to do the math fast enough, but I dunno.

If you mean to use a swarm of drones to attack a helicopter, I haven’t thought about that.
