Abstract

U završnom radu napravljena je usporedba primarnog radara i multilateracije. Opisan je objašnjen primarni radar te način njegovog funkcioniranja, objašnjeni su elektromagnetski valovi i njihova svojstva. Izvedena je formula radarske jednadžbe kojom se iskazuju parametri koji utječu na preciznost radara. Napravljen je izračun preciznosti korištenjem formule za preciznost te je prikazano kako rezolucija radara utječe na preciznost. Opisan je multilateracijski sustav te način na koji funkcionira. Prikazane su prednosti multilateracije i nedostatci. Prikazana je izvedba programa u Matlabu kojim se računa preciznost multilateracije i njena ovisnost o vremenu, te je nakon toga napravljena usporedba preciznosti radara i multilateracije.

Abstract (english)

In this work a comparison of precision of primary radar and multilateration is given. Radar and its principles are described, electromagnetic waves are explained along with their main properties. Radar equation that helps us better understand variables that affect radar precision is derived. Precision calculations are made, and it is shown how radar resolution affects the precision. Multilateration and its principles are shown so we can better understand the system and then a list of pros and cons of the system are presented. A program is made in Matlab that calculates precision of multilateration and shows how time error affects it. At the end we compare the two systems and give a summary.
