Suzhou Tianjing Yunhu Intelligent Technology Co., Ltd. (hereinafter referred to as Tianjing Yunhu) is the only innovative technology enterprise in China with full-airspace operational capabilities for fixed-wing aircraft in the field of airborne SAR. Tianjing Yunhu is deeply engaged in the research and development and system integration application of core technologies of synthetic aperture radar (SAR). It has independently mastered two core radar product lines: the Lingyun series frequency-modulated continuous wave and the Xiangyun series pulse system. It has also deeply adapted to a full range of fixed-wing flight platforms, building a seamless, all-altitude, all-weather Earth observation and all-domain operational system from low-altitude short-range to mid-to-high-altitude wide-area. It provides leading airborne remote sensing solutions for fields such as national defense security, emergency mapping, resource exploration, and ecological monitoring.
I. Low-altitude all-domain perception (0-600 meters): miniaturization, high maneuverability, and ultra-fine imaging
Targeting complex low-altitude environments below 600 meters, Tianjing Yunhu utilizes the CW15 VTOL fixed-wing UAV as its core platform, coupled with its self-developed LingYun system Frequency Modulated Continuous Wave (FMCW) miniature SAR, to create a lightweight, highly maneuverable low-altitude precision detection capability.
Platform: CW15 VTOL fixed-wing UAV, with a maximum takeoff weight of 16.5 kg and a payload capacity of 3 kg. Its modular folding design supports fully autonomous flight, offering advantages such as rapid deployment, flexible takeoff and landing, and long-endurance operation.
Core Payload: LingYun system (e.g., LY1B-Ku) miniature SAR, weighing only 2.7 kg, employs a Ku-band FMCW system, supports strip imaging mode, and can achieve single-polarization/full-polarization acquisition. Its imaging resolution is better than 0.2 meters, and it possesses real-time imaging and instant data acquisition capabilities.
Advantages: It is suitable for low-altitude and confined space operations, with fast response speed and low deployment cost. It can accurately acquire ultra-fine radar images of urban streets, near-ground targets, and small areas, meeting the needs of low-altitude fine detection such as battlefield reconnaissance, camouflage identification, near-ground security, and small-area mapping.
II. Mid-altitude wide-area detection (600-1000 meters): Multi-band, multi-system, high-efficiency coverage
For wide-area operations at mid-altitude (600-1000 meters), Tianjing Yunhu selected the CW25e electric fixed-wing aircraft as its platform. This aircraft is compatible with both frequency-modulated (FM) and pulsed SAR systems, enabling multi-band, large-area, and high-efficiency mid-altitude remote sensing.
Platform: CW25e electric fixed-wing UAV, with a service ceiling of 6000 meters, a payload capacity of 6.6 kg, and a maximum endurance of 240 minutes. It features high-altitude takeoff and landing capabilities, resistance to complex weather conditions, and stable cruise capabilities, making it suitable for continuous mid-altitude operations over a wide area.
Core Payload: The payload can flexibly carry both FMCW and pulsed X/KU/C-band SAR systems, covering multi-frequency band detection needs. It balances lightweight efficiency with long-range penetration, supporting wide-swath imaging, high-precision positioning, and multi-polarization data acquisition.
Advantages: Balancing detection range, coverage, and imaging accuracy, it can quickly complete efficient mapping, disaster monitoring, border patrol, and target surveys of areas ranging from tens to hundreds of square kilometers, achieving "one-stop" remote sensing information acquisition in a wide area of mid-altitude space.
III. High-altitude long-range strategic perception (1000-5000 meters): High power, deep penetration, full-band coverage
Targeting long-range strategic reconnaissance scenarios at mid-to-high altitudes (1000-5000 meters), Tianjing Yunhu utilizes the CW100 large fixed-wing aircraft platform, equipped with its self-developed Xiangyun series pulse-based SAR, to construct a strategic-level observation capability encompassing high altitude, long endurance, deep depth, and full spectral density.
Platform: The CW100 fixed-wing aircraft boasts advantages such as large payload, long endurance, and high cruising altitude, adapting to complex mid-to-high altitude weather conditions and long-distance flights, supporting large-scale, long-term, and deep-distance remote sensing operations.
Core Payload: The Xiangyun System pulse-based SAR covers multiple bands including X/KU/L, with the L-band exhibiting strong vegetation and soil penetration capabilities, enabling the acquisition of subsurface and subvegetated structural information. The system supports strip/spotlight imaging, single/full polarization acquisition, and integrates a high-precision POS system and professional imaging algorithms, resulting in clear, focused images with rich detail.
IV. Full-Spectrum Platform Expansion: Pegasus Fixed-Wing Aircraft, Empowering Diverse Scenarios
In addition to the core airspace operation system, Tianjing Yunhu has simultaneously completed in-depth adaptation of the Pegasus series of fixed-wing aircraft with its self-developed SAR, further expanding operational scenarios and mobility capabilities. The Pegasus UAV boasts advantages such as lightweight design, portability, high-altitude operation (takeoff altitude up to 5000 meters), and rapid relocation. Primarily equipped with the Xiangyun series L-band SAR, it meets the needs of special scenarios such as emergency rescue, field surveys, plateau scientific expeditions, and mobile reconnaissance, forming a full-platform coverage of "core airspace + specialized scenarios."
