Hello,
I am looking for a system that measures insect activity over a natural area such as a pond. Is there anything? I was thinking similarly to sonar to measure bird migration.
Best,
Valentin

These in-air ultrasonic detectors might do it, but you will need to check the sensitivity. If you want position you may need several and to signal process the results together.
For birds there are AI based classifies that can detect certain species.

For insects I am guessing image and video processing can be the most reliable approach.
Hallo Valentin,
there are some publication about the use of radar with insects (see below). I read that Biodiversity Center Naturalis in Leiden tried in 2019 a new insect monitoring method using cameras with AI :
Hogeweg L., Zeegers T., Katramados I. & Jongejans E. (2019). Smart Insect Cameras. Biodiversity Information Science and Standards 3 : e39241.

Best regards
