RDN-120 radar detection equipment is a fast response surveillance equipment based on Ku-band Linear frequency modulated continuous wave (LFMCW) and phased array technology. By integrating high-sensitivity phased array antennas and adaptive signal processing algorithms, it can effectively detect and continuously track low-altitude, slow-flying small aircraft targets (including drones, powered parachutes, delta wings, etc.), and simultaneously analyze the target's three-dimensional coordinates (distance/azimuth/height). Motion vector (speed/heading) and trajectory characteristics.
