A Telemetry-Based Post-flight Wind Profile Estimation Method for Air-to-Surface Missiles

다국어 초록 (Multilingual Abstract)

This paper presents a wind profile estimation method for test flight of a short-range air-to-surface missile. The method integrates the telemetry data (e.g., navigation data, fin control history), empirical regional wind profile data, and a high-fidelity flight dynamics simulator to infer on the vertical wind profile that the missile has experienced during the flight. The inference procedure works in a sequential fashion: (a) starting from the launching altitude, random winds are sampled from seasonal rawinsonde data, (b) the wind that matches best to the simulated trajectory using the telemetry data is chosen, (c) the updated wind distribution at the altitude is used as the prior information for the next altitude layer, and (d) this process is repeated. Simulation studies with high-fidelity simulator are performed to validate the proposed estimation method, highlighting its robustness against variation in wind profiles and flight conditions.
