Synthesis and analysis of the long range radar transmitting antenna feeding network

Discussion of the shaped beam pattern synthesis methods of a long-range radar antenna is presented. The optimised excitement current distribution of the transmitting array antenna is assumed as a base of the antenna feeding network design. Analysis of the hybrid waveguide-TEM line feeding network includes influence of the power dissipation and frequency change in the operational band. Monte-Carlo statistical analysis is used to predict the sensitivity of the antenna pattern parameters.
