使用雷达对中低空域的无人机和鸟类等缓慢移动的小目标进行城市监视是一项重大挑战。在强杂波中检测、定位和识别这种低可观测目标，既需要雷达硬件设计的创新，也需要处理算法的优化。为此，伯明翰大学已经建立了一个由两个L波段凝视雷达组成的试验台，以支持使用现实城市环境中的目标和杂波数据集进行性能基准测试。该试验台还为了解新颖的雷达架构如何增强雷达能力提供了工具。在大华大学校区安装雷达面临的一些挑战非常突出。详细的基准测试结果来自城市单基地和双基地现场试验，这些结果构成了与未来硬件改进进行性能比较的基础。描述了雷达与外部振荡器接口这一挑战的解决方案，并报告了与候选振荡器的独立台架测试。该试验台提供了对量子光子雷达性能进行详细分析的宝贵能力，并允许将其与传统振荡器技术进行比较，以便在城市杂波存在的情况下监视低可见目标。
Urban surveillance of slow‐moving small targets such as drones and birds in low to medium airspace using radar presents significant challenges. Detecting, locating and identifying such low observable targets in strong clutter requires both innovation in radar hardware design and optimisation of processing algorithms. To this end, the University of Birmingham (UoB) has set‐up a testbed of two L‐band staring radars to support performance benchmarking using datasets of target and clutter from realistic urban environment. This testbed is also providing the vehicle to understand how novel radar architectures can enhance radar capabilities. Some of the challenges in installing the radar at the UoB campus are highligted. Detailed benchmarking results are provided from urban monostatic and bistatic field trials that form the basis for performance comparison against future hardware modification. The solution to the challenge of interfacing the radar to the external oscillators is described and stand‐alone bench tests with the candidate oscillators are reported. The testbed provides a valuable capability to undertake detailed analysis of performance of Quantum photonic‐enabled radar and allows for its comparison with conventional oscillator technology for surveillance of low observable targets in the presence of urban clutter.
