Cylindrical elliptical coordinates
Elliptic cylindrical coordinates are a three-dimensional orthogonal coordinate system that results from projecting the two-dimensional elliptic coordinate system in the perpendicular $${\displaystyle z}$$-direction. Hence, the coordinate surfaces are prisms of confocal ellipses and hyperbolae. The two foci See more • Morse PM, Feshbach H (1953). Methods of Theoretical Physics, Part I.

WebWhat you've written down is the metric of flat space in spherical coordinates, which can be thought of as a warped product of the flat minkowskian two space $(t,r)$ with the unit sphere. This space is equivalent to the normal $(t,x,y,z)$ coordinates of standard special relativity under a coordinate transformation. There are other choices, however.
