Phased array radar

Jan 10, 2018

Phased array radar uses "phase shifter" to realize radar beam rotation. Phased array radar is divided into active and passive radar. 



Each of the active phased array radar transmitter is equipped with a transmitting/receiving components, each component can produce, receive, electromagnetic wave, so the bandwidth, signal processing and redundancy design is better than passive phased array radar has a great advantage. Because of this, it also makes the cost of active phased array radar expensive and more difficult to engineer. However, active phased array radar has unique advantages in function, which can greatly replace the trend of passive phased array radar.
