Comparison of Ballistic-Coefficient-Based Estimation Algorithms for Precise Tracking of a Re-Entry Vehicle and its Impact Point Prediction [PDF]

Journal of Astronomy and Space Sciences, 2012
This paper studies the problem of tracking a re-entry vehicle (RV) in order to predict its impact point on the ground. Re-entry target dynamics combined with super-high speed has a complex non-linearity due to ballistic coefficient variations.

High-Dimensional Diffusive Growth

, 2000
We consider a model of aggregation, both diffusion-limited and ballistic, based on the Cayley tree. Growth is from the leaves of the tree towards the root, leading to non-trivial screening and branch competition effects.

Ballistic Annihilation

, 2000
Ballistic annihilation with continuous initial velocity distributions is investigated in the framework of Boltzmann equation. The particle density and the rms velocity decay as $c=t^{-\alpha}$ and $=t^{-\beta}$, with the exponents depending on the ...

Problem of the reference height of the projectile trajectory as a reduced meteo-ballistic weighting factor

Defence Technology, 2014
This paper deals with the issue of preparation of the aiming angles with the use of tabular firing tables and needed determination of the ballistic elements μB (ballistic wind wB, wxB, wZB, ballistic (virtual) temperature τB, ballistic density ρB) from ...
