What is the purpose of developing ISRO’s MiniSAR (Miniaturized Synthetic Aperture Radar) at X – Band?
एक्स – बैंड पर इसरो के मिनीएसएआर (मिनिएचुराइज्ड सिंथेटिक रडार) को विकसित करने का मुख्य उद्देश्य क्या हैं?
Detailed Solution & Logic
To provide high - resolution X - Band radar imagery using compact airborne systems/ एयरबोर्न सिस्टम का उपयोग करके उच्च-रिज़ॉल्यूशन X-Band राडार इमेजरी प्रदान करना
Explanation / व्याख्या
-
MiniSAR (Miniaturized Synthetic Aperture Radar) is a compact radar system developed by ISRO for X-Band imaging, which is capable of producing high-resolution images.
-
It is primarily designed to map and characterize surface features such as craters, mineral deposits, and lunar surface features, especially for planetary exploration missions.
-
Being miniaturized, it can be deployed on small spacecraft or airborne platforms without adding much weight.
-
X-Band radars operate at a higher frequency (~8–12 GHz), which allows better spatial resolution compared to lower-frequency radars.
-
MiniSAR (Miniaturized Synthetic Aperture Radar) ISRO द्वारा विकसित एक कंपैक्ट राडार प्रणाली है, जो X-बैंड इमेजिंग के लिए सक्षम है और उच्च-रिज़ॉल्यूशन इमेज प्रदान कर सकती है।
-
इसका मुख्य उद्देश्य सतही विशेषताओं जैसे क्रेटर, खनिज जमा और चंद्रमा/ग्रह की सतह की विशेषताओं का मानचित्रण और विश्लेषण करना है।
-
इसकी संकुचित संरचना के कारण इसे छोटे उपग्रह या एयरबोर्न प्लेटफार्म पर तैनात किया जा सकता है बिना अधिक वजन बढ़ाए।
-
X-बैंड राडार उच्च आवृत्ति (~8–12 GHz) पर कार्य करता है, जो बेहतर स्थानिक रिज़ॉल्यूशन प्रदान करता है।
Extra Facts / अतिरिक्त तथ्य
-
First MiniSAR Mission: Deployed on Chandrayaan-1 to detect water ice at the Moon’s poles.
-
Miniaturization Advantage: Reduces payload weight and power requirements, making it suitable for small satellites and exploratory missions.
-
Applications: Lunar and planetary surface mapping, crater studies, ice detection, and topographic analysis.
-
Comparison: X-Band gives higher resolution than L-Band or S-Band radars, which are better for subsurface or vegetation studies.
