Maximum likelihood trajectory for the velocity of an artillery shell in free-flight

Abstract : The paper considers the problem of determining the translational velocity of an artillery shell from noisy information. To optimize the smoothness of the estimate which is to be used in a attitude observer through an analysis of its slope, the unknown is sought after under the form of an element of a family of possible curves, solely parameterized by their initial condition. The nonlinear dynamics of the velocity being a contraction, it is shown that a measurement bias is observable. The estimator statistical properties are studied when the number of measurement is increased.
