论文摘要
在雷达检测环境中运行的飞机的任务规划师通常涉及检测的可能性。检测的可能性是飞机姿势和雷达位置的非线性函数。此应用程序的当前路径规划技术假定飞机姿势是确定性的。但是，实际上，使用导航过滤器估算飞机姿势，因此包含不确定性。飞机的不确定性构成了检测概率的不确定性，但是在路径计划时通常不考虑这种现象。本文提供了一种将飞机姿势不确定性与单脉冲雷达检测模型相结合的方法，以帮助任务计划工作。该方法将检测概率和三个雷达横截面模型的表达线性化。然后，线性化模型用于确定飞机姿势不确定性引起的检测概率的可变性。本文的结果使用蒙特卡洛分析验证了线性化，并探讨了检测概率对飞机姿势不确定性的敏感性。
Mission planners for aircraft that operate in radar detection environments are often concerned the probability of detection. The probability of detection is a nonlinear function of the aircraft pose and radar position. Current path planning techniques for this application assume that the aircraft pose is deterministic. In practice, however, the aircraft pose is estimated using a navigation filter and therefore contains uncertainty. The uncertainty in the aircraft pose induces uncertainty in the probability of detection, but this phenomenon is generally not considered when path planning. This paper provides a method for combining aircraft pose uncertainty with single-pulse radar detection models to aid mission planning efforts. The method linearizes the expression for the probability of detection and three radar cross section models. The linearized models are then used to determine the variability of the probability of detection induced by uncertainty in the aircraft pose. The results of this paper validate the linearization using Monte Carlo analysis and explore the sensitivity of the probability of detection to aircraft pose uncertainty.
