摘要
为了减少数字信道化接收机的开发成本,提高吞吐量与处理速度,对被动雷达截获信号数字信道化接收机的结构进行了研究,提出了一种基于GPU的数字信道化接收机的实现方法。该高效结构不仅节省了硬件成本,缩短了开发周期,而且加快了处理速度,达到了准实时性。实验结果表明:基于GPU的运算平台与CPU平台相比较,处理速度提高一倍左右。
In order to reduce the development costs of digital channelized receiver and improve throughput and processing speed,the passive radar intercept signals on digital channelized receiver architecture has been studied,and a GPU-based digital channelized receiver implementations is presented.The efficient structure not only saves the cost of hardware,shortens the development cycle,but also speeds up the processing speed,reaching a quasi-real-time. Experimental results show that compared with CPU-based computing platform,the processing speed is improved by nearly an order of magnitude.
