Detection is usually the easier legal step
Passive monitoring is lawful for site owners in most jurisdictions, while transmitting jamming energy almost always needs specific authorization.
Jamming has side effects to engineer around
Broadband interference can affect Wi-Fi, telemetry, or GNSS timing nearby, so band selection, power, and antenna pattern matter as much as raw range.
Some threats defeat jamming entirely
Autonomous drones without radio links ignore RF jamming; radar detection plus interception or GNSS deception covers that gap.
A layered design resolves the trade-off
Detect first, confirm visually, then apply the narrowest effective effector under operator control.
