摘要
雷达数据采集在雷达数据分析和处理过程中起着至关重要的作用,如何高效、经济、高质量的进行数据采集是第一步。通过导航雷达JMA2254的实际信号分析,选择具有14位采样精度、65MSPS采样速率的AD9248采样芯片,很好地完成数据的采集,将模拟雷达信号转换为数字信号。通过实际电路板的制作与测试,完成了雷达信号的AD转换,并通过与实际雷达波形的对比以及图像的对比,检验采样的效果。
Radar data acquisition plays a vital role in radar data analysis and processing.How to achieve efficient,economical,high-quality data acquisition is the first step.By navigation radar JMA2254 actual signal analysis,a 14 sampling accuracy,65 MSPS sampling rate sampling chip AD9248 is chosen to complete data collection,and transform analog radar signal into a digital signal.By making and testing the actual circuit board,the radar signal AD conversion is completed.By comparison and contrast with the actual waveform radar images,the effect of test samples is tested.
