Abstract:
The uniformly accelerated reference frame described by Hamilton and Desloge and Philpott involves the observers  who perform the hyperbolic motion with constant proper acceleration. They start to move from different distances  measured from the origin O of the inertial reference frame K(XOY), along its OX axis with zero initial velocity. Equipped with clocks and light sources they are engaged with each other in Radar echo, Doppler Effect and Radar detection experiments. They are also engaged in the same experiments with an inertial observer  at rest in K(XOY) and located at its origin O. We derive formulas that account for the experiments mentioned above. We study also the landing conditions of the accelerating observers on a uniformly moving platform.
