In this thesis , one kind of the dual - band dual - polarized antenna is mainly researched 本文就主要針對一種雙頻雙極化天線進行研究。
Fixed radio systems - multipoint antennas - circulary polarized antennas for multipoint fixed radio systems in the 1 ghz to 11 ghz band 固定無線電系統(tǒng).多點天線. 1ghz - 11ghz頻段內(nèi)多點固定無線電系統(tǒng)用圓形極化天線
The test results accord with the simulation results well . grounded on the simulation and measurement , it proves that this antenna can be the dual - band dual - polarized antenna unit 最后,對天線陣元進行組陣分析,研究了天線單元間距對天線方向圖的影響,并得出了優(yōu)化的天線陣元間距值。
Firstly , the polarization characteristics of active multi - decoy of any elliptic polarized antenna jammer are presented and the polarization scattering properties of radar target are also discussed 首先詳細分析了任一橢圓極化天線有源假目標的極化特性,并探討了典型雷達目標的極化散射特性。
