As part of this project, we developed a stepped-frequency (SFCW) radar and a pulse radar, which operate in the frequency and time domains, respectively. Both radars were tested on a minefield, then mounted on a small land vehicle, and later on a hexacopter. The proposed project timeline was met, and all activities within the project were successfully completed.<\/p>\n\n\n\n<p>A frequency radar has been developed that uses standard telecommunication components and operates in the frequency range from 550 MHz to 2.7 GHz. The radar uses the principle of stepped frequency modulation and is capable of generating a frequency sweep in 10 ms using 200 frequency steps.<\/p>\n\n\n\n<p>A timing radar was also developed that uses the ultra-wideband (UWB) spectrum principle. The results showed that the radar is suitable for use with a ground vehicle, but it didn't perform well when mounted on a hexacopter. This is due to the uneven movements of the hexacopter, which affect the sampling mixer at the front of the radar.<\/p>\n\n\n\n<p>The final software was tested with a potential end user in Macedonia at the Military Academy, and at the test field in Benkovac. There's also a lot of interest from the demining center in Slovenia.<\/p>\n\n\n\n<p>The radar, attached to the hexacopter, is fully operational and capable of detecting landmines in affected fields both above and below the ground.<\/p>","protected":false},"excerpt":{"rendered":"<p>Povzetek Cilj tega predloga je razviti georadar (GPR) in ga pritrditi na lete\u010di objekt, imenovan heksakopter.
