Sensitivity of Single-Pulse Radar Detection to Radar State Uncertainty

Austin Costley, Randall Christensen, Robert C. Leishman +1

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…

Sensitivity of Single-Pulse Radar Detection to Aircraft Pose Uncertainties

Austin Costley, Randall Christensen, Greg Droge +1

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…

Analytical Aircraft State and IMU Signal Generator from Smoothed Reference Trajectory

Austin Costley, Randall Christensen, Robert C. Leishman +1

This work presents a method for generating position, attitude, and velocity states for an aircraft following a smoothed reference trajectory. The method also generates acceleromete…

A Closed-Loop Linear Covariance Framework for Vehicle Path Planning in a Static Uncertain Obstacle Fiel

Randall Christensen, Greg Droge, Robert Leishman

Path planning in an uncertain environment is a key enabler of true vehicle autonomy. Over the past two decades, numerous approaches have been developed to account for errors in the…

Zero-Error Tracking for Autonomous Vehicles through Epsilon-Trajectory Generation

Clint Ferrin, Greg Droge, Randall Christensen

This paper presents a control method and trajectory planner for vehicles with first-order nonholonomic constraints that guarantee asymptotic convergence to a time-indexed trajector…
