全固态天气雷达组合脉冲发射模式的研究与设计

Design and Realization of Combination Pulse Transmit Mode in Solid-State Weather Radar

为了提高全固态天气雷达发射机的平均功率,使雷达具有较远的探测距离,设计了一种全固态天气雷达组合脉冲发射模式。首先阐述了此方案的设计思想;其次针对试验用X波段全固态天气雷达系统(祥雨A型),设计了满足其探测要求的组合脉冲发射模式,最后将该组合发射模式方案运用到该全固态雷达系统中。结果表明,设计的组合脉冲发射模式可以保证此固态天气雷达在满足设定探测能力的同时,有较小的近距离盲区,这对固态天气雷达获取完整且准确的天气过程信息具有实际意义。

Based on the basic parameters of solid-state weather radar,a design method named combination pulse transmit mode is proposed,by which the blind zone of exploration can be obviously reduced. First of all,the design concept and thinking of this method was elaborated. After that,based on experimental X-band solid-state weather radar,a kind of combination pulse transmit mode which has satisfied the detection capabilities requirements was designed. In the end,this transmit mode project was applied in the experimental solid-state weather radar,and presented the results and detailed analysis of experiment. The results showed that: Designed combination pulse transmitted mode for solid-state weather radar would guarantee to meet the design requirements of detection capabilities,small close range blind zone. The design methods have prominent practical significances in terms of getting complete and accurate weather information with solid-state weather radar.
