... The antenna system . ... A military radar system, consisting of two identical radars, was transferred to the Institute of Solar-Terrestrial Physics (ISTP). ... The system features a two-channel transmit-receive antenna. ... By changing the phase difference in the channels, one is able to modify the shape of the total channels' beam in the angle-of-elevation plane. ... The total beam is controlled by introducing the phase signal into the excitation signal of one of the channels. ... Peak power.. ...
