The LDR-X-03(Four-Face Array) micro-small target detection rada employs an advanced all-solid-state, fully coherent, and pulse doppler system architecture. Featuring high reliability and robust signal processing capabilities, it enables round-the-clock detection, identification, and real-time early warning of "low, small, fast" targets such as drones and low-altitude aircraft, regardless of weather conditions. Utilizing a two-dimensional phased array scanning technology, this radar fully leverages the rapid beam control capabilities and multi-target processing efficiency of two-dimensional phased arrays.
