Abstract
We discuss the various possible physical processes able to provide the observed pulsar radio emission. The successful mechanism should be able to generate waves capable of (a) escaping from the pulsar magnetosphere and (b) satisfying the observational constraints.
The main attention is paid to the coherent curvature radiation which is the most appropriate mechanism from the observational point of view. Also, it may be the only possible mechanism that can operate at low altitudes, where the wave generation region is most likely located. We present the sequence of physical processes in the pulsar magnetosphere that generate radio waves that satisfy the observed features of pulsar emission.
