Miniature SAR (Miniature Synthetic Aperture Radar) is a miniaturized synthetic aperture radar system. Its core features are: small size and lightweight design, adaptable to platforms such as UAVs and small satellites, flexible and compact; capable of achieving sub-meter to centimeter-level high-resolution imaging; and all-weather, all-day operation. This has led to the increasingly widespread use of miniature SAR in civilian industries.

In modern warfare, there's a famous saying: "Artillery is the god of war." However, even the most powerful artillery is like "blind men touching an elephant" without accurate intelligence guidance.
Traditional reconnaissance methods are often limited by darkness, fog, or terrain. But now, a technology called "Synthetic Aperture Radar (SAR)" is revolutionizing artillery reconnaissance. It allows satellites hundreds of kilometers in space to clearly see a tank on the ground, providing clear battlefield images even in cloudless daylight or stormy nights.

Within the synthetic aperture radar (SAR) family, the W-band (75GHz-110GHz) stands out as a "detail hunter" in the field of precise perception due to its unique high-frequency advantages. Compared to traditional band SAR, the W-band achieves ultra-high imaging accuracy at the 0.1-meter level thanks to its extremely short wavelength, while also possessing lightweight characteristics, making it particularly suitable for airborne platform applications. This has opened up broad application prospects in both military and civilian fields, becoming an important support for technology to empower security and development.

Synthetic Aperture Radar (SAR) holds an irreplaceable position in the field of moving target detection due to its unique advantages of all-weather, all-day, and penetrating imaging. From vehicle and ship tracking in military reconnaissance to traffic flow control and disaster emergency response in civilian fields, SAR moving target detection technology has always been a core support for improving perception capabilities. Unlike static target detection, moving targets produce unique Doppler frequency shifts and positional offsets in SAR imaging, which constitute the core basis for detection but also bring many technical challenges.

By leveraging flexible platforms such as drones, high-resolution radar data can be acquired 24/7 under all weather conditions, providing a complete remote sensing data solution from acquisition and processing to analysis and application. Its core value lies in breaking the deployment limitations of traditional large-scale SAR systems, extending high-resolution radar remote sensing capabilities to small-scale civilian applications, and providing efficient and accurate spatial information support for various industries.

On the vast ocean, swells, as long-distance propagating wave phenomena, not only affect maritime navigation safety and port facility construction, but are also closely related to the global ocean energy cycle. How to accurately capture these movement trajectories hidden beneath the sea surface? L-band synthetic aperture radar (SAR) is becoming a "space-based eye" for monitoring ocean swells, thanks to its unique advantages.
