# KLT of radio signals from relativistic spaceships in uniform and decelerated motion

Chapter

## Abstract

It is well known that in special relativity two time variables exist: the coordinate time where

*t*, which is the time measured in the fixed reference frame, and the proper time τ, which is the time shown by a clock rigidly connected to the moving body. They are related by$$
\tau (t) = \int_0^t {\sqrt {1 - \frac{{v^2 (s)}}
{{c^2 }}} ds}
$$

(11.1)

*v*(*t*) is the body velocity and*c*is the speed of light (see [1, p. 44]).## Keywords
