摘要
利用双正交偶极子接收雷达回波信号,在天线的正交双通道中进行虚拟极化处理来增强信号、抑制杂波是改善目标信噪比的有效方法。文中介绍了虚拟接收变极化的原理,并运用虚拟极化实现了目标极化增强和杂波抑制,通过matlab仿真得到了直观的信噪比增强效果。
The Radar echo is received by bi-orthogonal dipole.Virtual polarization used two orthogonally channels in the antenna is an effective means for enhancing the target signal,suppressing the clutter signal and improving the target SNR.in this paper,the principle of virtual polarization is introduced,the enhancement of the target and suppression of the clutter are realized.At last,the effect of target SNR is given brieflyin the simulation of Matlab.
