The recently discovered phenomenon of pulsar radio emission intermittency attracts considerable attention of
observers and theoreticians. These challenging new types of radio pulsars emit sporadically on time-scales of hours,
to weeks and even years. Another peculiar sporadic radio emission phenomenon observed from pulsars are the Giant
Radio Pulses. These pulses are detected irregularly and are much more intense than regular radio pulses observed
from pulsars. Despite number of suggestions, no commonly acknowledged mechanism has yet been specified behind
these puzzling phenomena. Understanding these extraordinary objects would play a significant role for getting
closer to the development of a universal, single emission model for pulsars. We assume that these extraordinary
sources are “normal” radio pulsars and the reason for the emission intermittency is not the peculiar emission
generation mechanism, but rather the specific plasma processes that influence the regular character of radiation
detectability. These processes are naturally developing in pulsars magnetospheres and their influence for certain
circumstances must be leading to irregular disappearances of the pulsed emission from the line of sight of an
observer. The same processes can also develop in other types of radio pulsars, giving various patterns of observational
manifestations for different sources due to differences in their characteristic parameters. The detailed investigation
of the mentioned processes could lead to a self-consistent single theory for different types of radio pulsars, which is
the main objective of the present project.
