Abstract:

The general purpose of the work reported is to obtain the best possible feasible signal processing algorithms for estimating from radar data characteristics and trajectory parameters of bodies moving in the air. The report starts with an extensive set of numerical results showing the effectiveness of the simplified dynamics equations evolved in approximating pertinent characteristics of trajectories calculated by the BRL point-mass model. Next, a mathematical derivation of the optimal recursive algorithm for filtering and smoothing radar data, formulation for which was presented in the previous Quarterly Progress Report, is presented. A technique for evaluation of recursive filtering-smoothing algorithms by deterministic calculations is then presented.
