The cue that keeps the track
Passive RF classification and direction finding name the emitter and point the formation at it. When the airframe goes quiet, that bearing is what a tracking radar uses to hold the picture — dwell on a small radar cross-section, then the handoff to command and to the effector.
That layered picture is the counter-UAS concept of operations already running in exercises: sense on the move, cue the radar, let command and the effector finish. Mind & Signal’s sensor is the RF and machine-learning piece of that chain, priced to ride on the vehicle.
