Analysis of pulsed electromagnetic fields radiated by powerful sources

Abstract

Calculation method proposed for powerful sources radiation evaluation. Taken attention that in calculations it is necessary to use average radiated power. For example in case of radars it depends on two facts: radar radiates short radio impulses with long pauses between them and rotated antenna with narrow pattern of directivity in horizontal plane radiates into chosen point a short part of antenna's rotation period. Calculation is made for Thomson radar according proposed equations. It is shown that antenna in 5 m height radiates power flux density into level of man head more times smaller than permitted level according Lithuanian normative - 20,0 µW/cm2.
