Limitations of Radar Coordinates
arXiv:gr-qc/0409052 · doi:10.1142/S0218271805006961
Abstract
The construction of a radar coordinate system about the world line of an observer is discussed. Radar coordinates for a hyperbolic observer as well as a uniformly rotating observer are described in detail. The utility of the notion of radar distance and the admissibility of radar coordinates are investigated. Our results provide a critical assessment of the physical significance of radar coordinates.
