China researchers are developing passive radar systems—sometimes nicknamed “ghost radar”—that detect aircraft by listening to reflections from existing radio signals (TV, radio, cellular), rather than emitting their own radar pulses. Because passive radar doesn’t transmit, it’s harder to detect and can help track stealth aircraft. Claims that this technology could make a military “completely invisible” are overstated. In practice, passive radar is one tool among many, with limitations in coverag

Phased Array Radar is an advanced radar system that uses electronically controlled beamforming technology. It offers high precision, high sensitivity, and multifunctionality, and is widely used in military defense, aviation monitoring, meteorological detection, and other fields. Product Features: Electronically Scanned Beams: The beam direction is controlled electronically, allowing for rapid response to target changes without the need for mechanical movement of the antenna, improving reaction s

JUST IN: On March 14th, a Chinese engineer posted a tutorial explaining how to use passive infrared sensors to detect and track American fighter aircraft without triggering their radar warning receivers. Three weeks later, an American F-15E Strike Eagle is in a crater in central Iran. The IRGC says it was brought down by a “new aerospace defense system.” The system appears to be exactly what the tutorial described.The principle is elegant. Radar is active: it emits radio waves that bounce off th
