Right but it wouldn’t give you that color pattern and why would we be using chaff when radar spoofing is all electronic digital stuff? Well I guess it’s to give conspiracy people something to chat about.
I’m an old legacy radar guy, mostly FME type so I’m not very familiar with Doppler radar. But I would think the greens, yellows, and reds are a function of target density that the Doppler computer calculates and then adds the corresponding color. I may be totally off on this, so please correct me if I am.
