论文摘要
在基于地面雷达系统的检测威胁下运行的飞机的任务规划师通常与检测的可能性有关。当前在这种环境中进行路径计划的方法认为雷达状态（即雷达位置和参数）是确定性和已知的。实际上，雷达状态存在不确定性，这会引起检测概率的不确定性。本文提出了一种将雷达状态不确定性纳入单脉冲雷达检测模型中的方法。该方法将雷达检测模型相对于雷达状态线性化，并使用线性化模型来估算一阶检测概率的方差。本文的结果通过蒙特卡洛分析验证了线性化，并说明了检测概率对雷达状态不确定性的敏感性。
Mission planners for aircraft operating under threat of detection from ground-based radar systems are often concerned with the probability of detection. Current approaches to path planning in such environments consider the radar state (i.e. radar position and parameters) to be deterministic and known. In practice, there is uncertainty in the radar state which induces uncertainty in the probability of detection. This paper presents a method to incorporate the uncertainty of the radar state in a single-pulse radar detection model. The method linearizes the radar detection model with respect to the the radar state and uses the linearized models to estimate, to the first order, the variance of the probability of detection. The results in this paper validate the linearization using Monte Carlo analysis and illustrate the sensitivity of the probability of detection to radar state uncertainty.
