Radarji v vojaških letalih

V članku so predstavljeni osnovni koncepti delovanja radarjev. Razložena je radarska enačba in podrobno obravnavano usmerjanje signala z antenami. Na koncu je prikazano, kako radar izloči svojo tarčo iz zašumljenega signala z uporabo Dopplerjevega pojava ter obenem izmeri njeno razdaljo in hitrost.

Radar systems in military aircraft

This article presents the basic concepts of radar operation. The radar equation is explained and the steering of signals with antennas is discussed in detail. Finally, it is shown how radar extracts its target from a noisy signal using the Doppler effect, while simultaneously measuring its distance and speed.
