Reflecting signals of ISS

Almost thought I got lucky….

This is my first attempt at using ISS as the reflector whilst monitoring a 6m signal.

The image below shows an interesting reflection from ZS6TWB/b, but I seriously doubt that it was due to ISS.

I cannot see a reason for the two strange traces; it coincides pretty much with ISS being directly overhead with Doppler shift at near zero, but once again the issue is clouded with the Bi-static Radar theory.

Coming to think of it working and dealing with Doppler during satellite operation was relatively easy to understand by comparison.

I recon it would be better if the transmitting station was QRO and used a high gain antenna. Ideally both the transmitting station and the receiving stations antennas must be fully Azimuth/Elevation controlled.

ZS6A signals from ZS6TWB/b 6m beacon via ISS refelction?
