What is the main factor that determines the spatial resolution of a Side Looking Airborne Radar (SLAR) system?
- Orbiting altitude of the satellite
- Length of the antenna (correct)
- Slant range of the radar
- Frequency of the radar
Why does the azimuth resolution of a SLAR system deteriorate as the range increases?
Why does the azimuth resolution of a SLAR system deteriorate as the range increases?
- Due to the increase in the radar beam's angular spread (correct)
- Due to the decrease in the length of the antenna
