Radar can't effectively see the new low-altitude small fiber optic spool first-person drones that are redefining frontline war.

The solution is going to be multi-modal (optical + audio) and imperfect. The above poster is correct that an ordinary camera with computer vision (not an LLM, of course) is going to be part of the multimodal defense in depth.

Shahed-type one-way attack drones are important to defend against, but not as impactful in terms of frontline body count, given they just slam into a pre-programmed target.

The article and this thread are about shaheed style drones.

As far as I know, stopping fiber optic fpv drones leans more on physical barriers that catch the fiber (eg road nets) rather than trying to detect and destroy the drone. It’s usually too late by the time you can hear or see a drone that size.

My comment was about Shaheds like the article we are commenting on.

for what you are talking about, audio is a great option
