Ballistic missile precession frequency extraction by homomorphic filtering

In order to extract the precession frequency, which is an important feature parameter in ballistic missile target recognition, we first establish the dynamic Radar Cross Section (RCS) signal model for a conical ballistic missile warhead with precession motion. A homomorphic filter is designed to remove the scintillation effect in the RCS signal. Simulations show the practical usefulness of the proposed method in extracting an estimate of the precession frequency.
