I want to find out the distance between the centers of $2$ circles. Say, circle $1$ $(\theta,\phi)$ circle $2$ $(\theta,\phi)$
The radius of this circle is found using $d\tan(\theta)$ where $d$ is the range (different from radius)
$cd=\sqrt{(x_1-x_2)^2 + (y_1-y_2)^2 + (z_1-z_2)^2}$ is the formula I'm going to use to find out the distance between the $2$ points.
But can anyone help me in defining $x$, $y$ and $z$?
I know to convert it to Cartesian coordinates if say the points are $(r,\theta)$ where $r$ is the radius [$2$ dimensional]
$cd$ is a euclidean distance between the centre of circle#1 (formed due to angles $az(t,n),el(t,n)$ in space from transmitter $t$, at trial $n$ and distance $d$ away from origin) and circle#2 (formed due to angles $az(r,n),el(r,n)$ in space from receiver $r$, at trial $n$ and distance $d$ away from origin)
