Question

RISAT stands for:

• A. Radio satellite
• B. Radio navigation and ranging satellite
• C. Radar Imaging Satellite
• D. Resource Information Satellite

Hint:

Important Indian Remote Sensing Satellites: \[ \boxed{ \begin{aligned} \text{IRS} &\rightarrow \text{Indian Remote Sensing Satellite} \text{RISAT} &\rightarrow \text{Radar Imaging Satellite} \text{Cartosat} &\rightarrow \text{Cartographic Satellite} \text{Resourcesat} &\rightarrow \text{Resource Monitoring} \end{aligned} } \]

Answer 1

The Correct Option is C

Concept: RISAT is a series of Indian Earth observation satellites developed by the Indian Space Research Organisation (ISRO). These satellites use Synthetic Aperture Radar (SAR) for imaging, enabling observations during both day and night and under cloudy conditions.

Step 1: Recall the full form. \[ \boxed{ \text{RISAT} = \text{Radar Imaging Satellite} } \]

Step 2: Identify its application. RISAT satellites are mainly used for
• Agriculture monitoring
• Disaster management
• Surveillance
• Flood assessment
• Forestry Hence, \[ \boxed{\text{RISAT stands for Radar Imaging Satellite}.} \] Therefore, the correct option is \[ \boxed{(C).} \]
