🩺 PULSE CHECK
Should drones be allowed in public places like parks and beaches?
🎓 Key Terms
Sensor Fusion (SF): The process of combining sensor data into a single estimate of an object’s past path, present position, and future trajectory.
Supervised Machine Learning (SML): A training method that leverages “labeled” data, where each input is paired with the correct output, to learn how to predict outcomes.
📜 THE PRELUDE
The air hangs heavy, thick with the roar of hundreds of thousands of die-hard fans. In an instant, a rolling thunder of stomping feet ripples through the stadium seats. The football is snapped as the play clock ticks…ticks…ticks. Virtually every step, every shift, and every signal feels magnified with mounting tension.
Just as a route breaks open in the backfield, multiple whistles blow while a storm of yellow flags floods the field. The refs converge at the spot of the snap, with the stadium hanging in suspended silence, waiting for the ruling.
The jumbotron flickers to life: “FOREIGN OBJECT DETECTED IN FIELD AIRSPACE!” You scan the sky, eyes darting back and forth to spot the foreign object. But, there’s nothing: no beacon, no blades, and no buzz. Just empty air and confused murmurs spreading throughout the stadium seats.
When scrolling through social media later, you see a viral clip of the “Alta X,” an industrial-grade drone capable of carrying 35 lbs, hovering over the stadium before being intercepted by the city police department.
It’s what caused the delay! They were worried it could be armed with explosives. So, how did they even become aware of it? What enabled them to have such a rapid response?
👀 WHY DRONE DETECTION MATTERS
⦿ 1️⃣ Airports Grapple With Drones?
On Dec. 19th, 2018, over 1,000 flights were diverted or canceled at London Gatwick Airport, affecting more than 140,000 travelers for 33 hours. The widespread disruption was triggered after 170 drone sightings were reported near the only operational runway.
Unable to confirm whether the drone sightings were real or rumored, Sussex Police deemed the potential risks as “too serious to ignore.” These unmanned aircraft could cause catastrophic collisions, like damaging engines, shattering windshields, and tearing through wings. Within hours, the British Army deployed military-grade counter-drone weapons, including the “Drone Dome,” which jams a drone’s radio signals, forcing it to land.
Ultimately, the airport and the airlines lost roughly £1.4 million and £50 million, respectively. These financial damages led to the brief arrest of a British couple who were later cleared of all charges. In the aftermath, London Gatwick Airport invested nearly £5 million in a new counter-drone system. The entire security scare boiled down to collective panic with a lack of evidence.
⦿ 2️⃣ Drone Deliveries in U.S. Prisons?
It’s no secret that drones are often leveraged to airdrop contraband like drugs and weapons or smuggle luxury items like steak and crab legs, with inmates taking advantage of their ability to bypass physical barriers for illicit deliveries.
The FBOP, which manages the care, custody, and control of all federal prisoners, reported 497 drone incidents at U.S. federal prisons in 2024, representing a 21.6x increase since 2018. This massive surge isn’t only evident at the federal level. South Carolina reported 273 drone incidents in 2025, with the contraband seized from a single drone adding up to a “prison-economy value” of roughly $165,700. The contraband included ecstasy, tobacco, marijuana, knives, razors, and cell phones.
On Aug. 21st, 2024, the DEA unsealed two indictments against 23 alleged members of a sprawling, multi-year scheme to establish drone networks across multiple Georgia state prisons. The inmates relied on smuggled cell phones to send aerial photos to outside drone operators, coordinating illicit deliveries of drugs.
☁️ THE AI THAT TRACKS THE SKY
⦿ 3️⃣ AI Detects Drones We Can’t See?
Dedrone, which offers counter-drone defense, famously engineered “DedroneTracker.AI”: an airspace security software that identifies, investigates, and intercepts drones. It relies on a multimodal sensor suite that combines radio signals, radar reflections, and infrared light.
🔴 Signal Capture: What’s in the Air?
Nearly all consumer, commercial, and custom drones emit radio signals. They receive control commands from a remote pilot via radio links. These radio links include telemetry data like velocity, altitude, and orientation.
🟠 Signal Classification: What Kind of Drone?
Today, unmanned aircraft come in all kinds of shapes, sizes, and styles. They can have a set number of fixed wings or a varying number of rotors. They can be controlled using common radio protocols like MAVLink or uncommon radio protocols like ZigBee. For context, consumer drones rely on IEEE 802.11, which is similar to how digital devices wirelessly connect to the internet via Wi-Fi.
SML compares the radio signal signatures captured by RF Dedrone Sensors against DedroneDNA, a comprehensive catalog of the exact shapes, sizes, and styles of virtually any consumer, commercial, and custom drone, to accurately identify the model and manufacturer.
🟡 Signal Location: Where’s the Drone?
The SF Engines calculate the unmanned aircraft’s 3D position, generating a “time-stamped target track” from combined data collected via:
☎️ Radio Activity: Can return a noisy “blip,” detecting a momentary signal peak buried in static noise.
🟢 Signal Disruption: What Happens Next?
When an unauthorized drone is detected, a suitable response countermeasure is selected:
🚨 Cyber Cloning: Can manipulate navigational channels, controlling the drone to “return home.”
💥 Kinetic Killing: Can execute a “hard kill,” physically disabling the drone with high-energy lasers.
🔑 KEY TAKEAWAY
Until recently, detecting drones depended on physically spotting or audibly hearing them. Now, AI can identify the model and manufacturer of hundreds of consumer, commercial, and custom drones in real time by analyzing radio signals and radar reflections, providing public safety officials with critical minutes to respond.
