| 摘 要： | 针对利用X波段海浪雷达回波图像反演海浪参数(波高、波向、波周期)的需要,而海浪雷达回波信号的采集和存储是利用雷达回波图像序列反演海浪参数的必要前提,提出了基于PXI-9280 A/D采集卡对X波段海浪雷达回波进行采集的方案.具体介绍了PXI-9280 A/D采集卡的功能特性,海浪雷达回波信号样式,设计并完成了基于VC 6.0的采集和存储软件,并对使用该采集卡需要注意的实际问题给予说明.此外,还搭建了实验平台,给出了基于PXI-9280 A/D采集卡在我国南海某海域中采集数据并回放得到的海浪雷达回波图像,得到较满意的结果.

| Abstract: | With the needs of retrieval of parameters (wave height,wave direction,wave period) of ocean wave using X-band ocean wave radar echo images,while the acquisition and storage of ocean wave radar echo signal is the precondition for the retrieval of parameters of ocean wave,a scheme based on PXI-9280 A/D employed to sample the ocean wave radar echo signal is presented.In this paper,the function characters of wave height measurement based on X-band radar is introduced,the form of ocean wave radar echo signal is given,the software of acquisition and storage based on VC + +6.0 is designed and realized,the practical problem which should be cared in this card is also illuminated.Besides,the experiment platform is set,the playback radar echo images based on the data sampled by PXI-9280 A/D in the South China Sea area are given,the result is good. |
