Canada must be able to secure and protect the people and infrastructure in its urban environments. To do so, threats such as terrorist events and improvised explosive devices, in urban environments need to be identified early not only to safeguard the citizens and the infrastructure, but also to maintain the citizens' confidence in law and order and their trust in the government. In the case of threats that are mobile, it is also essential to accurately track and predict their kinematic states as they evolve over space and time. To detect such stationary or kinematic threats, sensors or signal sources such as cameras, radars, lidars, communication devices, radio and television stations, and cell phone towers can be used in an urban environment.In some urban scenarios, there might be an abundance of sensors due to ubiquitous cameras and cell phones, which could overload the communication and computational resources, or a dearth of accessible sensors due to the presence of buildings that block signal propagation, which would adversely affect the quality of threat detection and tracking. In either case, it is essential to strike a balance between (i) sensing, communication and computational resource utilization and (ii) the desired timeliness and accuracy of threat detection and tracking. This need to balance motivates the proposed research work to develop algorithms for optimal management of sensor, communication and computational resources as well as algorithms for threat detection and object tracking in urban environments using sensors and processors mounted on stationary or moving platforms. The proposed work will train a number of highly qualified personnel (HQP) in sensor and data processing with application to safety and security. In addition, the trained HQP can be employed and the resulting algorithms deployed in other fields such as autonomous vehicles, intelligent transportation and smart cities, which are of importance to maintain Canada's edge in today's high-tech world.

加拿大必须能够确保和保护其城市环境中的人民和基础设施。为此，需要及早识别城市环境中的恐怖事件和简易爆炸装置等威胁，不仅是为了保护公民和基础设施，也是为了维护公民对法律和秩序的信心以及对政府的信任。在移动威胁的情况下，随着它们在空间和时间上的演变，准确跟踪和预测它们的运动状态也是至关重要的。为了检测这种静止或动态的威胁，可以在城市环境中使用传感器或信号源，如相机、雷达、激光雷达、通信设备、无线电和电视台以及手机发射塔。在一些城市场景中，由于无处不在的摄像头和手机，可能会有大量的传感器，这可能会使通信和计算资源不堪重负，或者由于建筑物的存在阻碍了信号的传播，所以缺乏可访问的传感器，这将对威胁检测和跟踪的质量产生不利影响。在任何一种情况下，都必须在(1)监测、通信和计算资源利用与(2)所需的威胁检测和跟踪的及时性和准确性之间取得平衡。这种平衡的需要促使拟议的研究工作开发优化管理传感器、通信和计算资源的算法，以及使用安装在固定或移动平台上的传感器和处理器在城市环境中进行威胁检测和目标跟踪的算法。拟议的工作将培训一批高素质的传感器和数据处理人员(HQP)，并将其应用于安全和安保。此外，经过训练的HQP可以用于其他领域，如自动驾驶汽车、智能交通和智能城市，这些领域对于保持加拿大在当今高科技世界的优势具有重要意义。
