Yes, we heard that 10 times before. What we want to know is why didn't they start doing it 10-15 years ago. Once they implemented even partially digital rather than analogue processing, they can go beyond direct, instantaneous signal conversion (which limits you to displays like SSAZ, FRAZ, A-scope and the like because they have no memory) to raster display modes (which allows for waterfalls).
The DEMON itself is a waterfall. It has to store the time factor to have made the display it did, which means the tech to store time data is there - if you believe the display is more or less representative of what is available.
As for performance, even if you don't count the transient logging the difference is huge. I've managed to lock in DEMON at ranges that the SSAZ basically shows no signal! Imagine the extra BB sensitivity to be had if they skipped the DEMON processing when providing a waterfall! If the Russians even tried a waterfall once, the difference will be so massive there won't be an argument, at least from what I've seen. The difference will be like the shock the Sovs had when they found out the West could easily track their submarines because they actually worked on sonar and silencing.
