Non-invasive stand-off sensing for detecting, monitoring and localizing humans

距离或远程传感是一种非接触式非侵入式传感方法，通过发射波形（通常是电磁波）如雷达或被动（摄像机）来主动感知。当接触传感不可行时，如搜索和救援，军事和跨境安全应用，它是有用的。这也是一种经济的方式来监测多个病人在急诊科或老年人在家庭护理。虽然现有的大多数研究都集中在使用单个传感器或同一类型的多个传感器的组合上，但提议的发现拨款计划将考虑一套混合传感器，这些传感器单独使用不同的传感策略来实现可靠的传感。

Stand-off or distant sensing is a contactless non-invasive sensing methodology that sense either actively by transmitting waveforms (generally electromagnetic waves) such as a radar or passively (video cameras). It is useful when contact sensing is not feasible such as search and rescue, military and cross-border security applications. It is also an economical way of monitoring multiple patients in emergency departments or elderlies in home care. While majority of the existing research has focused on using single sensor or a combination of multiple sensor of the same type, the proposed Discovery Grant program will consider a suite of hybrid sensors that individually use different sensing strategies to achieve reliable sensing.
