This is a cool one! I don't know what we have here. It doesn't look like radar. Interference pattern with two pulsed point sources out of phase? Lots of radar pulses on the wider view.

It only shows up vertically polarized. Lots of radar pulses in the data also. I'm processing the raw data into RF FFTs which will take a while. This is 5.405GHz +- 100MHz BTW.

Russian AD site here. I don't think we are seeing the radars. That ramp tends to house 9L96-1 CHEESE BOARD or 91N6 BIG BIRD S-Band a NEBO-U TALL RACK VHF. However look at these two point sources pointed up at a GEO sat are sitting right here!!

Seems odd to be flying a Bayraktar TB2 around Kyiv at low altitude as tense as things are right now? Unfortunately friendly fire incidents have occurred in pretty much every large conflict.

I'm not 100% convinced about this incident.... Just feels off but the fog of war is really thick right now.

🇺🇦 Air Force confirmed now..

Why would Russia be interested in offshore wind farms? Here is my take based totally on informed speculation. Let’s talk about SCADA Supervisory Control And Data Acquisition.

SCADA is the control and sensor network for power grids. It can monitor things like Volts, Amps, Watts, RPM, Temp, Humidity, Alarms. It can control things like direction of the turbine, pitch of the blades, open / close circuit breakers, synchronization etc.

SCADA networks tend to be highly secure with intrusion detection and encryption. Tapping a fiber or breaking into a microwave link typically won’t give you the keys to the kingdom. However, physical access to the equipment at the RTU level could give you a way into the system.

Let's talk about Svalbard and why it's likely Russia was tampering with a undersea cable connecting the arctic island to the rest of the world. Svalbard has a large satellite ground station used mainly for polar orbiting satellites.

Ground stations near the poles are in view of polar orbiting satellites every orbit vs stations closer to the equator.

Many spy sats sit in polar orbit. Now you can see why Russia would be interested in tampering with undersea fiber optic cables from Svalbard to the mainland. Image: Wikimedia

Russian Baltic fleet was just talking USB and this came in and just analiated them... Looks like wide band PSK just a guess without looking into it.

That's Container OTHR just above... It's so strong i can see reflections of moving objects

Reflections of moving objects... Unsure is this is the insophere responding to sunrise, satellites, meteors, or aircraft... FIrst time i have seen reflections.

Different mode today at 17.050MHz Russian Container 29B6 radar 29Б6 Контейнер

Playing back the waveform mixing with the live signal out of phase seems like a plausible way to break the container. Again this is all virtual I'm not even on the same side of the planet! Streaming IQ from Poland to the US analyzing all in software!!
