摘　　要：介绍了一种自研的X波段全固态双线偏振多普勒天气雷达,并对其中的系统设计、脉冲压缩、补盲等关键技术,特别是脉冲压缩的影响及其解决途径进行了详细的论述。并与磁控管雷达进行了对比观测和分析,结果表明该固态雷达可以探测150 km范围内强于5 dBz的降水回波。The design of X-band solid-state Doppler weather radar of dual-linear polarization is described and the primary technology is discussed, such as system design, pulse compression, blind zone compensation, especially the influence caused by pulse compression and its solution. The precipitation detection capability of the X-band radar is compared with the magnetron radar. The result shows that the X-band solid-state radar can detect precipitation echoes stronger than 5 dBz within 150 km.
