Locating a radar in a plane > Given two located targets at $(x, y)=(- 2.0)$ and $(x, y)=(2,0)$. A radar, located in an unknown location of the $XY$ plane, and sends a pulse and in return receives pulses from the two t...
The condition implies that the difference between distances from the radar to the two targets is $$\frac{1}{2}\times\text{roundtrip time delay}\times\text You can also see that analytically by writing the equation $d_A=1+d_B$ (where $d_x=\text{dist}(\text{radar},x)$) and squaring it twice to get rid of roots

Is it possible to use a router with dd-wrt/openWrt/etc as a radar detector? Would it be possible to use a router with some kind of linux firmware and a laptop in a car as a radar detector?
No. For so many reasons. One obvious one: * 802.11 = 2.4, 3.6, or 5 GHz while: * X band = 8–12 GHz * Ku band = 12–18 GHz * K band = 18–27 GHz * Ka band = 26.5–40 GHz Layman's explanation of the above: The router cannot “tune” to the needed frequencies. (Then there's the DSSS vs burst detection, etc,...

Radar charts in Python - Plotly
A Radar Chart (also known as a spider plot or star plot) displays multivariate data in the form of a two-dimensional chart of quantitative variables represented on axes originating from the center. The relative position and angle of the axes is typically uninformative. It is equivalent to a parallel coordinates plot with the axes arranged radially.. For a Radar Chart, use a polar chart with ...
