What in the name of fuck is that bill. That’s one of the worst pieces of legislation I’ve seen in a longer while. Companies and open source communities will immediately catch that an employee is trying to sabotage their system on behalf of the government by means of code review and version control history. The programmer will be questioned, then likely fired or ostracized in case of open source works and the code will hit the bin. This idiotic… thing will accomplish nothing but harm their own citizens who will now be treated like potential therats and denied employment opportunities.
On a funnier note, every time Australia introduces some horrible tech-related bill I remember this beautiful clip summarising just how well politicians understand technology.
The radar you’re talking about is a pulse-doppler radar. It doesn’t see things the same way your eyes (or a synthetic-aperture radar for example) do and it’s not down to filters. A P-D radar observes and measures the Doppler effect which only occurs when the object is moving and determines the contact’s velocity, heading and altitude based on that. A jet flying vertically at 0 GS would probably be detectable, although this would be difficult since, as you said, it’s not moving directly towards or away from the radar.
