The radar detection and positioning system integrates microwave spintronics sensors with EM signal processing to achieve ultra-sensitive detection and accurate positioning. Using Magnetic Tunnel Junction (MTJ) devices, it detects microwave radiation through spin-dependent tunneling, enhancing range and direction finding. The system fuses EM wave direction-finding algorithms with RADAR principles to determine azimuth, elevation, and distance with high precision. It supports multi-frequency operation, adaptive calibration, and modular integration for UAVs, vehicles, or fixed installations. Compact, low-power, and resilient to noise, it delivers next-generation radar capabilities suitable for defense, navigation, and industrial sensing applications.
