SAR, or miniature synthetic aperture radar, is a miniaturized synthetic aperture radar system. It builds upon traditional SAR by reducing system size, cost, and power consumption, making it more suitable for smaller platforms or specific applications.
Small airborne MiniSAR systems can be integrated into UAV platforms to achieve flexible, high-resolution remote sensing imaging. They can also rely on orbital motion platforms to support flexible system configuration and broadband signal generation and acquisition. Indoor scaled-down model imaging experiments can be used to complete equipment debugging and verify the product's imaging capabilities.
Ka-band MiniSAR system
Application Case: The track platform developed by Suzhou Tianjing Yunhu Intelligent Technology Co., Ltd. integrates the LY1A standard Ka-band payload and possesses the following technical advantages:
1. Platform Performance
Maximum load capacity of 10kg, 4-hour endurance, and support for remote-controlled constant-speed gliding;
The system operates in a stable environment with long endurance, significantly improving data acquisition efficiency.
2. Core Design
The standard Ka-band fully polarized miniature SAR is developed based on the Frequency Modulated Continuous Wave (FMCW) system, supporting low-altitude, wide-swath, high-resolution imaging;
Equipped with a high-precision motion compensation algorithm, optimized for the attitude jitter of the lightweight platform under wind speeds of level 3 (3.4-5.4 m/s), ensuring imaging stability;
3. Extended Functions
The accompanying software system supports ground corner reflector calibration, enabling:
Fully polarized scattering matrix inversion;
Accurate measurement of target RCS (radar cross section).
Ka-band Orbital SAR System
The indoor imaging system, combined with a high-precision sliding rail, eliminates environmental interference through a stable motion path, enabling precise verification of interferometric data and millimeter-level deformation and displacement monitoring.
