A laser ranging system on a UAV is targeted by a modulated light source that injects fabricated returns, causing the vehicle to perceive an obstacle where none exists. An engineer proposes rejecting any detected object that fails to persist across consecutive scans and to appear at a physically plausible position given the vehicle’s own motion. Evaluate the proposal.

Two prediction approaches are compared for a UAV’s altitude channel. Model 1 predicts the next altitude reading as a weighted combination of recent altitude readings. Model 2 predicts it from the vehicle’s state and the thrust commands the controller issued. An adversary begins slowly biasing the barometer while the controller commands a hold. Which model is better positioned to detect this, and why?
