The Four-face Two-Dimensional Phased Array Radar is a high-performance active phased array radar system,specially designed to meet requirements of all-domain situational awareness., The system employs a coordinated mecha-nism of four independent phased array panels, achieving 360 full-sky coverage without blind spots and supportingmulti-dimensional target detection. Operating effectively in complex cluttered environments and under all-weatherconditions,the radar enables continuous detection,tracking,and classification of abnormal targets within the protectedzone. It features high-precision measurement capabilities, providing rea-time output oftarget parameters such as range,azimuth,elevation,velocity, and attributes.This radar delivers a comprehensive solution for low-altitude airspace moni-toring and management,featuring omnidirectional sensing,intelligent analysis, and precise, reliable target tracking.
