Airport Surveillance Radar System
Abstract: With the rapid development of modern warfare Low-Altitude Penetration Weapons and the gradual opening of my country's low-altitude airspace, civil air defense has put forward an urgent need for low-altitude and ultra-low-altitude early warning capabilities. The low-altitude early warning radar uses advanced Phased Array Technology to control the beam of distributed T/R components to achieve elevation scanning, and improves measurement accuracy through vertical multi-wave position scanning and intra-wave position and difference beam angle measurement capabilities. The system adopts the wave position allocation method of 8 elevation beams. In order to ensure sufficient pulse accumulation, the low beam is processed by MTD of three groups of 6-pulse filters, and the high beam is processed by 3-pulse MTI. In terms of processing algorithm, we adopt the design and algorithm of high clutter improvement factor, use clutter map and various threshold detect...
