Abstract

Na početku rada, uvode se osnovne postavke kako je raketa smještena u prostoru preko
koordinatnih sustava, te kako je opisano gibanje rakete modelom 6DOF (six degrees of freedom),
tj. modelom sa šest stupnjeva slobode. Također, objašnjava se gibanje glave rakete u odnosu na
gibanje cilja kako bi se dao bolji uvid u navođenje rakete na cilj. Osim toga, prikazan je primjer
lako prijenosnog raketnog sustava te glavni dijelovi rakete čije su uloge dodatno objašnjene.
Dalje je pokazana shema simulacijskog modela, koji se izvršava u simulacijskom okruženju
MATLAB kako bi se pojasnili odnosi između skripti i funkcija simulacije. Na kraju su prikazani
rezultati simulacije gađanja cilja u dolasku, uz vjetar i bez vjetra, a nakon toga i gađanje cilja u
odlasku, također uz vjetar i bez vjetra. Neki od prikazanih rezultata simulacije su brzina rakete,
udaljenost glave rakete i cilja tijekom simulacije i ostali segmenti vezani za navođenje rakete na
cilj.

Abstract (english)

At the beginning of the thesis, fundamental preferences, which describe position of missile in
coordinate systems and movement of missile by 6DOF (six degrees of freedom), are introduced.
Also, movement of the head of the missile in relation to target is explained to give better insight
on guidance of the missile at the target. Besides that, it is shown the example of man-portable
air-defense system and its main parts' purposes are explained. Further, scheme of simulation
model is shown, which is executed in software environment MATLAB to explain relations
between scripts and functions. At the end of the thesis, results of the simulation hitting the target
in approaching, with and without wind, and hitting the target in receding, with and without wind,
are shown. Some of shown results are velocity of missile, distance between the head of the
missile and the target during simulation and other segments linked to guidance of the missile at
the target.
