单脉冲雷达对飞机姿态不确定性的探测灵敏度
Sensitivity of Single-Pulse Radar Detection to Aircraft Pose Uncertainties
摘要：
在雷达探测环境中工作的飞机的任务规划者经常关心探测的概率。探测概率是飞机姿态和雷达位置的非线性函数。当前用于该应用的路径规划技术假定飞行器姿态是确定性的。然而，在实践中，使用导航滤波器估计飞机姿态，因此包含不确定性。飞行器姿态的不确定性导致检测概率的不确定性，但在路径规划时通常不考虑这种现象。本文提供了一种方法，结合飞机姿态的不确定性与单脉冲雷达探测模型，以帮助任务规划的努力。该方法线性化的检测概率和三个雷达截面模型的表达式。线性化的模型，然后用于确定由飞机姿态的不确定性引起的检测概率的变化。本文的结果验证了线性化使用蒙特卡罗分析和探索的敏感性的检测概率的飞机位姿不确定性。
英文摘要：
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.
