Phased Array Radar System for High Precision Long Range Multi-Target Tracking Detection

  Phased array radar is a phase-controlled electronic scanning array radar. Its ability to quickly and accurately switch beams enables the radar to complete the scanning of the entire airspace within 1 minute. The so-called phased array radar is a radar array composed of a large number of identical radiating units. Each radiating unit is independently controlled by wave control and phase shifters in phase and amplitude, and can obtain accurate and predictable radiation patterns and beam pointing. When the radar is working, the transmitter distributes power to each antenna unit through the feeder network, radiates energy through a large number of independent antenna units, and performs power synthesis in space to form the required beam pointing.

  General radar beam scanning is achieved by rotating the radar antenna, which is called mechanical scanning. Phased array radar uses electrical methods to control the direction change of the radar beam to scan and discover targets. This method is called electronic scanning. Although phased array radar cannot rotate the electromagnetic lobe by rotating the antenna like other radars, it has its own way, which is to use phase shifters to realize electromagnetic petal rotation.

  Phase-controlled array radar uses electronic scanning. Its beam pointing is flexible, so that scanning can be carried out quickly, and can also achieve tracking of multiple targets simultaneously. Cooperate with computers to effectively discover, explore and track targets in multiple directions and at different heights. Phase array radar is a system that can replace the work of multiple special radars. It can form multiple beams at the same time and control them independently. These beams can search, explore, identify, track, illuminate targets, and guide missiles. Because of this, it can greatly reduce the equipment of weapon systems, and improve the system's maneuverability. This phased array radar has become an ideal choice for modern air defense, security and reconnaissance missions due to its advanced technical indicators, stable environmental adaptability and flexible networking capabilities.
