Abstract:Radar s sintetično odprtino omogoča doseganje boljše resolucije kakor radar z realno odprtino, saj lahko z uporabo enake antene s SAR-radarjem sintetiziramo večjo odprtino. V magistrskem delu smo zasnovali radar s sintetično odprtino. V okviru tega smo iz osnovnih gradnikov najprej sestavili radar s frekvenčno modulacijo in z zveznim valovanjem (FMCW). Za sestavljen radar smo izdelali program za obdelavo podatkov. FMCW-radar smo nato namestili na kolo in posneli odziv, ki smo ga programsko obdelali v dvodimenzionalno SAR-sliko. Za obdelavo oziroma združenje podatkov v SAR-sliko smo uporabili algoritem migracije razdalje (RMA).
Keywords:zasnova radarja, radar s frekvenčno moduliranim zveznim signalom (FMCW), algoritem migracije razdalje (RMA), radar s sintetično odprtino (SAR)

Title:Synthetic Aperture Radar Design
Abstract:A synthetic aperture radar enables better resolution than a real aperture radar, as we can synthesize a larger aperture with the SAR using the same antenna. In the master's thesis we designed a synthetic aperture radar. We began by assembling a frequency-modulated continuous wave (FMCW) radar from the basic building blocks. We created a data processing program for the assembled radar. We then mounted the FMCW radar on a bicycle, recording its response; the latter was processed by the program into a two-dimensional SAR image. The range migration algorithm (RMA) was used to process or focus the data into a SAR image.
Keywords:radar design, frequency-modulated continuous wave (FMCW) radar, range migration algorithm (RMA), synthetic aperture radar (SAR)
