通用软件无线电外设USRP NI 2920是目前主要用于软件无线电应用的软件定义收发器，本文采用该外设设计了一个高分辨率的L波段软件定义雷达系统。增强的可用带宽，由于千兆以太网接口，被利用，以获得更高的倾斜距离分辨率相对于现有的软件定义的雷达实现。一个特定的LabVIEW应用程序，执行雷达操作，进行了讨论，并成功的验证，以证明所提出的软件雷达架构的准确的目标检测能力。特别是，采用金属板作为参考结构，在距设计雷达系统不同距离处进行了室外和室内试验，并成功地对实测回波进行了处理，准确地揭示了目标的正确位置，预测斜距分辨力为6m。
The Universal Software Radio Peripheral USRP NI2920, a software defined transceiver so far mainly used in Software Defined Radio applications, is adopted in this work to design a high resolution L-Band Software Defined Radar system. The enhanced available bandwidth, due to the Gigabit Ethernet interface, is exploited to obtain a higher slant-range resolution with respect to the existing Software Defined Radar implementations. A specific Lab VIEW application, performing radar operations, is discussed, and successful validations are presented to demonstrate the accurate target detection capability of the proposed software radar architecture. In particular, outdoor and indoor test are performed by adopting a metal plate as reference structure located at different distances from the designed radar system, and results obtained from the measured echo are successfully processed to accurately reveal the correct target position, with the predicted slant-range resolution equal to 6m.
