told ya - if they can do it on the ground they can do it in a balloon too

Here ya go folks - as predicted - Chinese quantum radar.

Scruffy has a 100% track record with scientific predictions. Scruffy's nose is keen that way.

Now you know what those green lights from space are about, and what "comms" is about when Austin complains about a domain gap.

Hardly a prediction when Raytheon have been working in the quantum area since at least 2020 and Zero Hedge reported 10 days ago on other technologies being employed now , rather than at some point in the future.
That report covered the ALTA balloon programme ,Lidar Observation from a platform,
Multi Spectral Imaging ( similar to Lidar) and various development areas in Delivery Platforms .

All interesting material but any fool can " predict " if that actually just means keeping up with reporting sources .
I could post early material or a near daily basis but this raises the questions of how many here could and would read it and how many could/ would be able to understand it .
The usual time /effort/ reward equation .

You touched on the key point.

Raytheon is "working on it".

China "already has it working".

Quantum radar is not LIDAR, btw.

For an introduction to what's going on here, you need to understand adaptive demodulation using Kalman filters.

This applies to the situation where you know neither the carrier nor the modulation type, and the modulations are possibly changing in real time.

There's a pretty big literature on this by now, you can Google it.

Ask yourself: what is the single prominent behavior that distinguishes the quantum world from other worlds?

LIDAR works on reflection. Pulsed lasers for ranging.

Quantum radar works on absorption and re-emission.

If you send a packet of entangled photons at the target you get near-ideal information, including the radar evading stealths and etc.

The Chinese are pretty good with what they've learned. Look:

Physicists stored data in quantum holograms made of twisted light

Light that travels in corkscrew-like paths provides a way to make holograms that store large amounts of data in ultrasecure packages.
