Which is more advanced, digital array radar or solid-state active phased array radar?

Digital array radar is certainly more advanced.

Digital array radar is also a phased array radar, but compared with the traditional phased array radar, it abandons the traditional digital phase shifter and attenuator and a large number of power cables and control cables.

It is a digital phased array radar with digital beamforming technology for receiving and transmitting. On the one hand, it is more flexible in system resource scheduling and beam pointing control, and it is easy to realize multi-function and multi-task. Large dynamic range of signal receiving and processing, strong anti-interference ability; Various irradiation beams with special shapes can be formed to realize controllable spatial power distribution; By forming multiple beams at the same time, wide-angle spatial coverage can be realized, and multiple targets can be searched and tracked at the same time, with high data rate. On the other hand, because digital array radar uses multi-channel parallel digital processing technology to generate and receive signals, its system structure is very complex, and the massive signal data generated in real time requires high data throughput and processing ability of the system. The complexity of system control, resource scheduling and target data processing brought by multi-function and multi-task brings great challenges to the design and engineering implementation of digital array radar data processing system.

Each radiator of active phased array radar is equipped with a transmitting/receiving module.

Each module can generate and receive electromagnetic waves by itself. The basic unit of digital array radar is called Digital Array Module (DAM).

It is a comprehensive front-end module with integrated design of multi-channel transceiver components, which has the functions of high power transmission, small signal reception, digital signal generation and reception.

Simply put, digital array radar is a kind of digital radar that can be controlled by software, and the future development will be software radar. By solving several key technologies in the integrated electronic information system, such as broadband radiation aperture, broadband T/R component, mass data transmission and processing, multi-task resource manager, etc. Its application range is much wider than that of traditional active phased array radar. If digital array radar is used, what fire control radar, communication radar, search radar, early warning radar? ...

Because of the high adaptability and multifunctional characteristics of digital array radar system, digital array radar can undertake all kinds of complex tasks at the same time, including long-range warning detection, target search, target indication, accurate target tracking, missile guidance and other tactical tasks. It is an important development direction of a new generation of phased array radar.

At present, China's digital array radar is leading in the world, and will soon be used in various national defense and civil fields such as shipboard, early warning aircraft, long-range early warning, space-based early warning, weather early warning and so on!

Because it is more professional, so the information is from the public information on the internet, I hope I can help you.
