apparently passive radar is governed by some US Munitions list:
US Munitions List, Category 11(a)(3)(xxvii):
Bi-static/multi-static radar that exploits greater than 125 kHz bandwidth and is lower than 2 GHz center frequency to passively detect or track using radio frequency (RF) transmissions (e.g., commercial radio, television stations);
What he has done is awesome. Yes, I misunderstood the title at first too, but that was more than made up by the care and attention put into building this app. Building things for your own kids just for the fun of it is what parents do.
The title of the the piece/submission would be well served by calling it a simulated radar. I, like I suspect many others, clicked on it because I was honestly intrigued by the concept of some sort of homebrew radar. Setting that bar and then seeing that it's some API results plotted on a simulated radar screen is a bit of a letdown.
Submission is clickbait. It's a cool project, sounds like fun and I'm sure their kid likes it, but the root post is not wrong.
I clicked because I was excited to see the story of their unexpected interaction with the FCC and FAA (or local equivalents) due to putting out that much EM radiation in those spectra. But no. Still cool, though.
I don't know, phones are addicting and getting a toddler hooked seems like a disservice. There's so many educational things the author could be giving their toddler and they're teaching them to have their eyes glued to their screen from such a young age...

Phones are not addicting. Algorithmically manipulated services are addicting.

Like how to use one's skills and passions to develop a product for their beloved child?
What's new about phones is NOT that things are manipulated so that we want more of it. "News" have been around for centuries and they've always been manipulated to give most people outrageous stuff to consume.
What's new about phones is that A) they are an effectively infinite source of stuff and B) it takes 2 seconds to get them from our pocket.
So you're blaming addiction on optimization by evil services, but in reality the problem are the phones themselves: they make it too easy to "get more".
I see where you're coming from, it's a totally reasonable point. I tried from the outset to make it more like a toy that prompts you to look at the real world once it gives you information. But, this is a totally reasonable stance
I like that it involves more than just scrolling. There's the thing about searching and finding it in the sky and the questions which can arise from this, like where did this plane come from.
Even if it were a real radar you'd still be looking at a screen in order to make use of it.
This is probably an alt account for jocaal who posted a nearly-identical, unuseful comment and then deleted it. Then this one magically appeared right after, to again point out what's already obvious to the rest of us.
Nonetheless, a great little project that inspires wonder in a kid!
