Abstract.** A
method of calculating the energy characteristics of an phased array antenna
above the irregular earth surface by the parabolic equation method is presented.
The phased array antenna is a periodic system of unidirectional radiating
elements with centers lying in one plane. The radiation pattern of the radiating
element embedded into the phased array is assumed to be known and is weakly
directional. The model of the earth surface is a half-space with profile varying
in two directions. The proposed technique can be applied to calculation of the
sanitary-protective zone and the restriction zone of the phased array.
