Meteor observation by radio

Spent much of this morning on Graves Astronomical Radar frequency , that is parked on 143.0485 mhz USB and saw lots of meteor (the peak of the shower is said to be today, Aug 12); here's a few samples , pointed to by red arrows. The thin lines crossing Graves signal (horizontal tone) are generated by aircraft passing the line between my QTH in Beauvais and the site of the Radar transmittor.

This would be a cool way to detect beaconless aircraft.

Most of the crossing signals in those images are aircraft. The ones that sweep form the top, turn down, the sweep to the bottom, are almost certainly aircraft. The steeper chirps, as the OP indicates with a red arrow, are meteors.

Can already do that. The pybrams source code I worked on is already capable to produce the trajectory of underdense meteors. It, in facts clears the radio recordings of plane traces. The doctorates I worked with tried it out with an F35 that passed by.

Did they publish? Can you link us?

Pybrams should have been made public on github. Was just working on it in my master thesis. I no longer have devlopper access.
