The Phased Array Antenna Calibration System is designed to perform precise testing and calibration of radar seeker phased array antennas in operational field environments. Using amplitude and phase data acquired during factory or in-field maintenance tests as a reference, the system calibrates phased array antennas of radar guidance heads under real-world conditions. It combines high accuracy with operational simplicity, making it suitable for both laboratory and field applications. This system minimizes setup complexity and equipment volume while maintaining calibration precision, offering a cost-effective solution for phased array antenna validation and maintenance.
