为了解决现有天气雷达垂直分辨率低和探测周期长的问题
本文旨在分析了雷达的两种采样方式CPS(Contiguous Pairs Sampling)与IPS(Independent Pairs Sampling)
设计了基于IPS的交互式波束多路转换扫描方式
这种扫描方式适用于速度谱宽较大的灾害性天气探测
同时对现有多普勒天气雷达体扫模式中的降水模式VCP11(Volume Coverage Pattern)进行了改进
提出了适于相控阵天气雷达在俯仰上采用三波束同时扫描的方案
最后对两种VCP进行了评价.
Characteristics of the nonintertia fast directionality
easily form multiple beams of phased array radar antenna make it have more function than the conventional radar.In this article
both CPS scanning pattern and IPS scanning pattern are analyzed.An interlaced beam multiplexing scanning method based on IPS mode is established
which is fit for the weather phenomena with larger spectral width.After the shortcomings of presented Doppler weather radar VCP11 mode are analyzed
its scanning methods are improved
accordingly
the ideal scanning mode is derived
that is
three beams scanning is used in pitch at the same time.This scanning mode can reduce remarkably scanning time than using single beam scanning.
