I. What is a miniature SAR?
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.
II. What is Target Recognition?
Target recognition, specifically, refers to the process of automatically or interactively detecting, classifying, identifying, and even confirming targets of interest using fused data acquired by the Lingyun series SAR system through algorithms.
Land Target Recognition: In the military field, this involves identifying the type, orientation, and even status of military vehicles such as tanks, armored vehicles, and missile launchers. In the civilian field, it can identify types of illegal structures, engineering machinery, and geological hazards (landslides, fissures), etc. KU-band SAR can penetrate thin camouflage nets, and combined with optical imagery, significantly improves the accuracy of target classification in complex environments.
Maritime Target Recognition: Detecting ships, it can identify ship types (such as oil tankers, container ships, warships), estimate their tonnage, and determine their heading and speed based on high-resolution imagery. It can be applied to maritime smuggling and illegal immigration.
Aerial Target Recognition: It can perform detailed identification of aircraft on airport tarmacs, distinguishing aircraft types, counting numbers, and monitoring scheduling status. Especially in the KU band, the Lingyun series can achieve 0.1-meter resolution imaging.
III. Advantages of KU-Band SAR
The KU-band is crucial for achieving fine target identification. Its short wavelength characteristics bring two core advantages: first, it can achieve ultra-high resolution down to 0.1 meters, clearly revealing the fine structure of targets; second, it is extremely sensitive to the scattering characteristics of complex structures. Whether it's the sharp edges of man-made targets or subtle surface movements and material differences, they all form unique and stable feature maps in KU-band images. This makes KU-band SAR irreplaceable in military camouflage identification and civilian fine mapping, especially in scenarios such as vegetation penetration, urban 3D modeling, and micro-variable analysis, where feature stability and interpretation confidence are significantly superior to other bands.
IV. Our Lingyun Series Products
The Lingyun series adopts a frequency-modulated continuous wave operating system, featuring a hybrid strip and spotlight operating mode, covering multiple bands including X, Ku, C, Ka, L, and W. It has single-polarization and full-polarization modes, real-time imaging capabilities, and optional interferometry functionality.
It can be applied to camouflage assessment, battlefield reconnaissance, point target characteristic identification, integrated reconnaissance and strike, surveying and mapping, agriculture, forestry, marine monitoring, geology, deformation monitoring and other fields.
