Recently, Suzhou Tianjing Yunhu Intelligent Technology Co., Ltd. successfully completed multiple high-precision remote sensing imaging test flights using its independently developed pulse-based X-band synthetic aperture radar (SAR) on an unmanned aerial vehicle (UAV) platform. This test flight primarily verified the environmental adaptability, system stability, and high-definition imaging performance of the Tianjing Yunhu pulse-based X-band SAR. Its outstanding 0.2-meter resolution marks a key breakthrough for the company in the field of micro SAR R&D, demonstrating the leading strength of my country's domestically produced micro SAR equipment and providing a high-performance, highly reliable dedicated technical solution for the field of low-altitude intelligent remote sensing.
I. Deepening Core Competencies: Tianjing Yunhu Pulse-Based X-Band SAR – Technological Strength Forges Core Competitiveness
Suzhou Tianjing Yunhu Intelligent Technology Co., Ltd., a pioneer in the field of micro SAR, focuses on the independent R&D, production, and remote sensing services of SAR equipment. It possesses two core technology routes: pulse-based and frequency-modulated continuous wave (FMCW), covering multi-band products. Leveraging its fully independent R&D advantages, it has broken free from import dependence and created high-performance remote sensing equipment suitable for diverse domestic scenarios. The pulse-based X-band SAR tested this time is a core product of Tianjing Yunhu's Xiangyun series, specifically customized for UAV platforms. With "high precision, all-weather operation, strong stability, and lightweight" as its core characteristics, it embodies the company's years of technological accumulation and has become a core breakthrough equipment in the field of low-altitude remote sensing.
II. Core Technology Analysis: The Core Advantages of Pulse-Based X-Band SAR
The Tianjing Yunhu Pulse-Based X-Band SAR, with its unique technical design, has established a differentiated competitive advantage in the industry, highlighting the following core strengths:
Dual Advantages of Band and System: Utilizing the X-band (9–10GHz), it combines high precision with strong penetration, easily penetrating clouds, fog, rain, snow, smoke, and shallow vegetation. It completely overcomes limitations imposed by lighting and weather conditions, enabling uninterrupted imaging around the clock and in all weather conditions. This perfectly compensates for the shortcomings of optical remote sensing in complex environments, solving the pain point of traditional remote sensing being "dependent on weather conditions."
Industry-Leading Imaging Accuracy: The successful test flight verified that this SAR system can stably output high-resolution radar images better than 0.2 meters, clearly identifying fine targets such as ground vehicles, building outlines, small facilities, and terrain textures. The imaging details are sharp, the boundaries are clear, and the data accuracy fully meets the high-end needs of high-precision mapping, target identification, and refined monitoring.
Lightweight and Highly Adaptable: Utilizing a low-power, modular design, it achieves lightweight integration while maintaining high performance. It can flexibly adapt to various UAV platforms without requiring complex modifications to the carrier, making deployment convenient, operation efficient, and significantly reducing remote sensing operation costs.
Fully Independent and Domestically Produced: Core chips, imaging algorithms, and hardware components are all independently developed. This not only improves the equipment's reliability and ease of maintenance but also ensures independent control of core technologies, breaking the technological monopoly of foreign products and demonstrating the rising strength of domestically produced SAR equipment.
Multi-Mode Adaptability to Diverse Needs: Supporting multiple operating modes such as striping, spotting, and in-orbit interferometry, it can flexibly switch working modes according to different scenarios such as emergency mapping, land surveys, and disaster assessment, achieving "one machine for multiple uses" and adapting to diverse industry applications.
