发展有效的感知与规避系统是无人机系统在国家空域运行的关键挑战。一个关键问题是实现在足够的范围内检测潜在目标，以实现与适用于UAS的轻质低成本传感器的低碰撞概率。我们提出了一个封闭的形式的分析方法来设计的最小所需的传感范围的基础上，最坏情况下的碰撞遇到的几何形状。使用500英尺的最小安全距离和几种不同飞机的已知速度，发现使用松弛参数δr = 0.0354时，所需的最小传感距离约为1.861 km。我们证明，这是一个可行的结果，通过描述一个雷达传感器原型，达到所需的最小感应范围。
Development of effective sense and avoid systems is a critical challenge for operation of unmanned aircraft systems (UAS) in the National Airspace. A key issue is achieving detection of potential targets at sufficient range to achieve a low probability of collision with lightweight, low cost sensors suitable for UAS. We present a closed form analytical approach to designing the minimum required sensing range based on worst-case collision encounter geometries. Using a minimum safe distance of 500 ft and known velocities for several different aircraft, this minimum required sensing range is found to be approximately 1.861 km using slack parameter of δr = 0.0354. We demonstrate that this is a feasible result by describing a radar sensor prototype that achieves the required minimum sensing range.
