随着城市环境中恶意被动感知风险的增加，需要相应地提高对隐私保护无线电频谱防御方法的研究。第一个研究项目的全部成果是一个主动和被动雷达系统的数字模型，该系统可用于根据目标轨迹、位置和速度矢量生成合成雷达数据。为了开始捕捉不同可能的运动模式的范围，根据伦敦大学学院一个房间的测量结果，建立了三个室内轨迹的模型。随后，移动被动和主动接收机以研究双基地几何形状对跟踪精度的影响。虽然通过实验试验尝试了真实世界的数据捕获，但没有成功，将其留在未来的工作中。

With the increasing risk of malicious passive sensing in urban environments, there needs to be aproportionate rise into research on privacy-preserving radio frequency spectrum defence methods. Thecompleted deliverables of the first research project are a digital model of an active and passive radar systemwhich can be deployed to generate synthetic radar data in response to target trajectory position and velocityvectors. Three indoor trajectories were modelled based on measurements taken in a room at UCL to begin tocapture the range of different possible movement patterns. Subsequently, the passive and active receiverswere moved around to investigate the effect of bistatic geometry on tracking accuracy. While real-world datacapture was attempted through experimental trials, they were unsuccessful and are left as future work.
