What is the main purpose of developing ISRO’s MiniSAR (Miniaturized Synthetic Aperture Radar) at X-Band?
Show answer & explanation
Correct answer: C
Explanation
Correct Answer: To provide high-resolution X-band radar imagery using compact airborne systems.
Explanation:
- What is MiniSAR? It is a 'Miniature Synthetic Aperture Radar' developed by ISRO that operates in the X-band.
- Main Objective: Its primary goal is to capture high-resolution images of the Earth's surface using small and lightweight platforms.
- Key Feature: Compared to traditional radar systems, it is significantly smaller and lighter, allowing it to be easily deployed on small satellites or drones (UAVs). It is capable of providing clear imagery even through clouds, fog, or in darkness.
Additional Technical Information:
- Advantage of X-band: Due to its high frequency, X-band radar (8–12 GHz) is capable of discerning very fine details, which is crucial for military surveillance and disaster management.
- Applications: It is used for agricultural mapping, urban planning, border security, and monitoring disasters such as floods.
