摘要
针对某型单脉冲雷达的高速数据采集需求,提出了一种单脉冲雷达并行数据采集方案。对系统的分布式处理结构和信号适配接口进行了分析。为解决采样率和数据传输能力的矛盾,讨论并实现了带通采样技术。为保证数据传输的正确性,研究并实现了异步传输技术。实验结果表明,系统在处理能力和采集速度等方面均达到了预期水平,并已应用于部队训练。
A design of Parallel High Speed Data Acquisition System for monopulse radar to meet the requirement of multi-channel high speed data acquisition of monopulse radars is proposed. The distributed topology and adapter to the monopulse radar of the system are analyzed. To address the contradiction between sample rate and data transmission, bandpass sampling technology. To ensure the data validity is discussed and implemented, discussed and implemented asynchronous transmission technology. Test results show that the system meets the requirements of processing capability, data acquisition speed etc. , and the system has already been applied to military training.
