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.

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.

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.

合成孔径雷达（Synthetic Aperture Radar, SAR）和逆合成孔径雷达（Inverse Synthetic Aperture Radar, ISAR）是两种先进的雷达技术，它们在成像原理、应用场景和目标特性等方面存在显著差异。

In power system operation and maintenance, the safety monitoring of transmission lines has always been a major challenge. Traditional manual inspections are inefficient and risky, while unmanned aerial vehicle (UAV) optical inspections are often limited by weather and lighting conditions. Now, a cutting-edge technology originating from aerospace remote sensing—airborne synthetic aperture radar (SAR)—is bringing revolutionary changes to the monitoring of potential hazards in transmission lines.
