【摘要】 便携式雷达具有移动性强的特点,文章基于蓝牙技术设计了一种无线数据传输系统,可以把便携式雷达采集到的数据实时传输至电脑保存,取代了便携式雷达与与电脑间的有线连接,极大的方便了便携式雷达的使用。文章利用CSR公司的单芯片蓝牙模块结合FPGA与USB技术设计了系统的硬件电路,并且采用蓝牙技术构建了点对点的数据无线传输平台,最后编写了应用程序将雷达数据无线传输至电脑并保存成文件。系统有效传输速率可达到700kb/s,在无遮挡情况下传输距离可达100m,在穿透普通墙壁情况下传输距离可达3m,并且在便携式雷达缓慢移动情况下仍能保证数据的稳定传输。更多还原

【Abstract】 The portable radar has the advantage of high mobility.In this paper a wireless data transmission system,which can transmit real-time data collected by portable radar to computer and save the data,has been designed.As a substitution of the connection wire between portable radar and computer,the system has brought much convenience to the use of portable radar.Based on FPGA and USB technology,the paper designs the hardware of the system by using the single-chip Bluetooth IC manufactured by CSR Corporation.A Bluetooth point-to-point data wireless transmission platform has been built.Moreover,the application program is developed for real-time radar signal sampling,and it can transmit the data to PC wirelessly.The valid transmission rate is 700kb/s. And the transmission distance can reach a hundred meters with no obstacle,but when transmitting through the wall it falls off to three meters.Even if the portable radar is moving slowly,this system can also ensure the stable data transmission.更多还原
