本文介绍了一种基于UCL ARESTOR平台的双主被动雷达实验装置。这是一款基于Xilinx射频系统芯片(RFSoC)设备的多功能射频传感器。该系统能够作为有源雷达、无源雷达和宽带电子监视接收机使用。实验结果表明，利用2.4 GHz无源雷达实验和5.8 GHz有源雷达模式，可以同时观测感兴趣的目标。白皮书中包括定制设计的射频前端以访问更高频段的详细信息，以及现场可编程门阵列(FPGA)内开发的处理流水线的信息。分析和讨论了目标签名的比较以及如何最好地利用这两种模式。本文感兴趣的对象是同时被两种模式感知的人。
In this paper we present a dual active and passive radar experimental setup that uses the UCL ARESTOR platform. This is a multi-role RF sensor based on a Xilinx Radio Frequency System on a Chip (RFSoC) device. The system is capable of operating as an active radar, passive radar and wideband electronic surveillance receiver. Experimental results are shown that leverage 2.4 GHz passive radar experiments along with a 5.8 GHz active radar mode that are operating simultaneously observing a target of interest. Details of a bespoke designed RF front-end to access higher frequency bands are included within the paper as well as information on processing pipelines developed within the Field Programmable Gate Array (FPGA). Comparison of the target signature and how both modes could be best utilised are analysed and discussed. The target of interest within this paper is a person walking while being sensing by both modes simultaneously.
