摘　　要：本文提出了一种FM/CW(调频连续波)系统设计方案,通过一个单口径复合天线实现了多种极化组合的收发功能,使原收、发两天线合一,体积重量减小,测量中采样面积扩大,增强了极化组合探测功能.最后还介绍了这种设计在地面微波散射计中的应用.A design of a FM/CW system is presented. The transmitting and receiving functions with several polarization combinations are realized by using a mono-aperture compound antenna. The volume and weight are reduced and the area of the sample in the measurement is increased in comparison with the system in which both transmitting and receiving antennas are used. The ability of detection with different polarization combination is improved. This design has been used to the ground based microwave scatterometer.
