Tianjing Yunhu | Frequency Band Characteristics Determine Imaging Performance: Analysis of Imaging Effects and Selection of Airborne SAR Payloads in X/C/Ku/Ka Bands
Synthetic Aperture Radar (SAR), as a core technology of active microwave remote sensing, overcomes the limitations of optical remote sensing caused by illumination, clouds, fog, rain, and snow, enabling all-weather, 24/7 Earth observation. It plays an irreplaceable role in fields such as land surveying, disaster monitoring, military reconnaissance, marine surveillance, and agricultural and forestry resource surveys. The selection of the operating frequency band for SAR payloads is a core element determining the system's imaging resolution, ground feature identification capability, environmental adaptability, and penetration performance, directly defining the application boundaries and technological advantages of the equipment.

Tianjing Yunhu | Unmanned Aerial Vehicle-borne Synthetic Aperture Radar (SAR): A Revolutionary Solution for Crop Lodging Monitoring
Lodging is one of the major disasters restricting the stable and high yields of major grain crops such as corn and wheat. Extreme weather such as strong winds and torrential rains can easily cause root and stem lodging, directly resulting in reduced yields, decreased quality, and significantly increased harvesting and compensation costs. Traditional manual inspections are inefficient, and optical remote sensing depends on sunlight and weather conditions, making it difficult to meet the needs for rapid, accurate, and all-weather monitoring after disasters.

Tianjing Yunhu | Emergency Rescue: SAR and LiDAR Collaborative Operations
SAR uses microwaves to "observe changes and measure dynamics," while LiDAR uses lasers to "measure shapes and determine locations." One is static and the other is dynamic; one is coarse and the other is precise, forming a complete closed loop of emergency remote sensing capabilities.
