A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- Posts must be original/unique
- Be good to others - no bigotry - including racism, sexism, ableism, homophobia, transphobia, or xenophobia
- Adhere to Lemmy's Code of Conduct

RADAR: RA(dio) D(etection) A(nd) R(anging)
It doesn’t rely on self transmission. It can but you can detect and range other sources without generating it yourself.
That’s just what the acronym means, it doesn’t describes the actual process. I don’t think there is a single RADAR that doesn’t have a transmitter. At that point it would just be a… radio.
Passive radar?
Fair enough, though I would argue that’s a very specific subtype of radar and anyone saying “radar” refers to the type that is used in 99.999% of the cases.
Yeah probably true. I only thought to look it up because I knew active and passive sonar was a thing.
