The JY-50 Passive Radar is a modern radar system designed for covert surveillance, target detection, and tracking without actively transmitting signals. By utilizing ambient radio frequency emissions such as commercial broadcast, communication signals, or other electromagnetic sources, the JY-50 provides a low-probability-of-intercept (LPI) capability, making it ideal for airspace monitoring, early warning, and tactical reconnaissance.
