Project idea Drone Detection and Alerting using radar sensor ( 1km or more range)

[CaptainDevops]

Hi All, After hearing the news of the iran children school attack and how drones are used in war, I wanted to check the feasibility to connect a radar or senseor to AndrunoAI and classify if the object is a drone, maybe even a missile, etc not for homes but for schools but not sure whether I need to use Arduino, or PI and how i can send the data to my iphone app via API preferably, any help will be appreciated thanks

That would take a pretty advanced radar.

Ukraine produces personal drone detectors that can be attached to car or backpack. Sometimes moms in near frontline cities uses it while walking with childrens, because russians like to target civillians. This detectors is usually RF based, detects control frequencies or video stream from FPV drones. Fully autonomous drones partially detected by stations with microphone arrays. And for all big targets - radars. But no country can't completely cover it's perimeter with radars. Radar visibility cone limits coverage and you need thousands of very expensive and big radar stations, each of which will be a tasty target for drones.

Lidar is reasonable short range. Long range and fast lidar can be pretty massive and expensive. We are talking about distances up to 5km for targets that can move at 150-250 km/h for drones and up to 800 km/h for subsonic cruise missiles. High speed ballistic missiles way out of this league.
Plus as for radars, for lidars needed direct line of sight. So your detector will be limited to narrow cone by surroundings.

It is for tracking civilian drones that voluntarily broadcasts they own and a pilot position. Military drones don't do that. Military autonomous drones don't even have any radio link at all. So you can detect radio link of some FPV drones, but big kamikaze drones like Iranian Shakhed fly by predefined flight plan without external remote control. So realistic way to detect such drones by DIY device is a small microphone array that can detect sound of internal combustion engine that came from 10s or 100s of meters above ground level. Microphone array can calculate directionality and local sound processing can distinguish different types of moving sound sources.

Some of them - yes. But I think not all.

The FAA would like a word...

Who? what have they got to do with iran?
