About this image

Following the alert of increased activity found on the 14th in daylight (UK) i checked my Excel analysis and there are strong reflections over this period.
The "temperature" chart shows the number of reflections counted in 1 hr bins from Aug-11 to Aug-15. The spectrum is a 2.5 min period at 0802UT on the 14th August. I don't understand all the complexity, but the prolonged signal on the RHS has a regular beat superimposed. This is caused by the scanning mode of the radio transmitter.

The spectrum has time (duration) on the X-axis, and frequency shift on the Y-axis which would be an indication of direction or velocity (I believe).
