摘　　要：研究风廓线雷达系统优化设计问题,由于我国地处东亚季风区,气候条件复杂,因此天气预报误差大。采用传统的跟踪气球的方法,获得高空风信息的时间与空间分辩率低和传统的风廓线雷达模拟接收机结构繁琐且信号处理精度不高。为解决上述问题,提出了一种新的风廓线雷达中频数字系统设计方案,通过对方案进行设计和仿真,验证了方案的可行性,能够满足风廓线雷达实时信号处理的要求,并证明系统具有可靠性高、实时性好、可扩展性和低成本等优点。Research the optimization of the design problem of Wind Profile Radar（WPR） system. China is loca- ted in East Asia monsoon region, the climatic conditions are complex, therefore, the weather forecast errors are large. The shortcomings are that the tracking balloon of detecting wind information of high altitude has a low temporal and spatial resolution, and the analog receiver adopted by traditional WPR receiver is cockamamie and the precision of signal pretreatment is not high. To solve the above problems, a novel WPR intermediate frequency（IF） digital system was studied in this paper. The design and simulation demonstrate that it can satisfy the requirements of WPR real- time signal processing. The system brings the advantages of high reliability, high real time, high extensibility and low cost.
