What radar technology does the MQ-9 use?

The MQ-9 is equipped with advanced radar technologies that include Synthetic Aperture Radar (SAR) and Ground Moving Target Indicator (GMTI). SAR is a sophisticated form of radar that captures high-resolution images of ground targets by moving the radar platform, which helps in mapping and reconnaissance missions. This capability allows the MQ-9 to create detailed images regardless of weather conditions or time of day, making it invaluable for intelligence, surveillance, and reconnaissance operations.

Moreover, the GMTI functionality allows for the detection and tracking of moving targets, such as vehicles or personnel, which is critical for assessing enemy movements and strategies. The combination of these two radar technologies enhances the operational effectiveness of the MQ-9, giving it a significant edge in situational awareness and target acquisition.

In contrast, conventional radar is limited in resolution and capability, while infrared radar is a different technology that focuses on temperature differences rather than detailed ground imaging. Ultrasonic radar systems are not utilized in aerial platforms like the MQ-9, as their functionality is primarily applicable in different fields such as underwater exploration or industrial applications. Thus, the advanced capabilities provided by SAR and GMTI technologies make the answer C the correct choice.
