In this paper, we investigate two topics related to mitigating the effect of radar bias in ballistic missile tracking applications. We determine the absolute bias between two radars in polar coordinates when their relative bias is given in rectangular coordinates. Using this result, we then obtain the optimized steady-state filter to handle the random bias.

ted to allow efficient ballistic missiles , the paper describes a recently developed ted estimation/guidance design paradigm n several innovative concepts that provides satisfactory homing performance against ly maneuvering targets. The new paradigm veloped and tested first by using a simplified constant speed interception scenario model. paper the integrated estimation/guidance m is validated ...

Abstract In the shatter regime of a Whipple shield, large central fragment makes significant contribution to damage-causing capacity debris cloud. Herein we present feasible scheme for identification and measurement this propose an alternative approach ballistic limit equation (BLE) deducing in based on fragment’s characteristics. This BLE is compared with phenomenological BLE, JSC Ryan curve. ...

Current study reported a facile method to investigate the effects of stacking sequence layers of hybrid composite materials on ballistic energy absorption by running the ballistic test at the high velocity ballistic impact conditions. The velocity and absorbed energy were accordingly calculated as well. The specimens were fabricated from Kevlar, carbon, and glass woven fabrics and resin and wer...

We analyze diffusion processes with finite propagation speed in a non-homogeneous medium terms of the heterogeneous telegrapher’s equation. In limit infinite-velocity we recover results for process. The process exhibits rich variety regimes including hyperdiffusion, ballistic motion, superdiffusion, normal and subdiffusion, different crossover dynamics characteristic complex systems which anoma...
