Path Planning with Uncertainty for Aircraft Under Threat of Detection from Ground-Based Radar

no code implementations8 Jul 2022 Austin Costley, Greg Droge, Randall Christensen, Robert C. Leishman, James Swedeen

The error budgets identify the contribution of each source of uncertainty (e. g., sensor measurement noise, radar position uncertainty) to the overall variability in the probability of detection.
