A mathematical model was described which was devised to study the dynamic response of the thorax of mammals to rapid changes in environmental pressure and to non-penetrating missiles impacting the rib cage near the mid-lateral point of the right or left thorax. Scaling procedures f 'imiiar animals were described relating, for a given degree of darn'age, the body mass of the animal to various pa...

∗ Both authors are visiting professors at Macedonian Military Academy, and have significant contribution in teaching/research activities in the field of intelligent missile systems Abstract. We have developed a simulation model of homing-guided anti-aircraft or surface-to air (SA) missiles SAM, suitable for research, development and testing of different guidance and control laws, obtained from ...

one of the main concerns of processing algorithms used in synthetic aperture radar (sar) with a ballistic motion is the compensation of all phase errors in the data received from the target to achieve a clear picture of the target. in this article, by using range doppler algorithm and phase-gradient auto focus algorithm, imagery in one sar with a ballistic motion is considered according to the ...

The article provides an analysis of the state affairs in field U.S. missile defense, inherited by Biden administration from previous administration. U. S. defense policy can be roughly divided into three components: homeland regional and advanced developments related to these both parts. Conclusions are made about prospects policy, taking account such factors as views experts think tanks close ...

In this paper, we derive the sufficient and necessary stability conditions for rolling missiles with velocity orientation autopilot. For mathematical derivation, linear time-invariant models are established. Structures of autopilot nonrolling introduced. addition, effects structure parameters on discussed. Furthermore, methods associated actuator dynamics, static decoupling presented to improve...

A new approach to guiding a swarm of missiles using an on-line evolutionary algorithm to optimise the flight paths is introduced. The missiles are flown via intermediate points which are adjusted dynamically by the evolutionary algorithm, then towards the point of impact with the target, thus altering the trajectory shape. Evolutionary algorithms are robust global optimisation techniques and ar...
