    "abstract": "We give a closed expression for the Minkowski (1+1)-dimensional metric in the\nradar coordinates of an arbitrary non-inertial observer O in terms of O\u0027s\nproper acceleration. Knowledge of the metric allows the non-inertial observer\nto perform experiments in spacetime without making reference to inertial\nframes. To clarify the relation between inertial and non-inertial observers the\ncoordinate transformation between radar and inertial coordinates, also is\ngiven. We show that every conformally flat coordinate system can be regarded as\nthe radar coordinate system of a suitable observer for a suitable\nparametrization of the observer worldline. Therefore, the coordinate\ntransformation between arbitrarily moving observers is a conformal\ntransformation and conformally invariant (1+1)-dimensional theories lead to the\nsame physics for all observers, independently of their relative motion.",
