Interplanetary scintillation and pulsar pulse statistics

The effect of interplanetary plasma on pulsed pulsar radiation passing through is considered. pulses two rotating radio transients (J0609+16, J1132+25) and a (B0320+39) detected the Large Phased Array (Pushchino observatory) were analyzed. It shown that in observations at frequency 111 MHz, elongations 20o-40o, both an increase decrease number received are observed. change explained by distortion energy distribution due to scintillation. These changes observed qualitative agreement with expected dependence scintillation index sources elongation. Analytical expressions obtained allow estimating effective modulation from individual for power energy.
