Digital array radar is of course more advanced.
Digital array radar is also a phased array radar, but compared with traditional phased array radar, it abandons traditional digital phase shifters and attenuators as well as a large number of power cables and control cables.
It is a digital phased array radar that uses digital beamforming technology for both reception and transmission. On the one hand, it has more flexible system resource scheduling and beam direction control, and is easy to achieve multi-function and multi-tasking; Signal reception and processing has a large dynamic range and strong anti-interference ability; it can form various specially shaped illumination beams to achieve controllable spatial power distribution; by forming multiple beams at the same time, it can achieve wide-angle airspace coverage and target multiple targets Simultaneous high data rate search, tracking and other features. On the other hand, since the digital array radar's signal generation and reception processing all adopt multi-channel parallel digital processing technology, its system configuration is very complex. The massive signal data generated in real time places extremely high requirements on the system's data throughput and processing capabilities. It is multi-functional. The complexity of system control, resource scheduling and target data processing brought by multi-tasking poses a huge challenge to the design and engineering implementation of digital array radar data processing systems.
Each radiator of the active phased array radar is equipped with a transmitting/receiving component.
Each component can generate and receive electromagnetic waves by itself. The basic unit that constitutes the digital array radar is called the digital array module (DAM).
It is a comprehensive front-end module with integrated design of multi-channel transceiver components. It has the functions of high-power transmission, small signal reception, digital signal generation and reception and other functions.
Simply put, digital array radar is a digital radar that can be controlled by software. Its future development will be software-based radar, which solves the problems of broadband radiation aperture, broadband T/R components, Many key technologies such as massive data transmission and processing and multi-task resource managers have a much wider application range than traditional active phased array radars. If digital array radars are used, the original fire control radars, communication radars, search radars, etc. Early warning radars... can all be replaced, which can reduce the size and number of radars, reduce electromagnetic interference between various radars, and greatly improve work efficiency.
Due to the highly adaptive capabilities and multi-functional characteristics of the digital array radar system, the digital array radar can simultaneously undertake various complex missions, including remote warning detection, target search, target indication, and target precision. Various tactical missions such as tracking and missile guidance are important directions for the development of the new generation of phased array radar.
my country's current digital array radar is currently leading the world, and will soon be used in various national defense and civilian fields such as ship-based, early warning aircraft, remote early warning, space-based early warning, weather early warning, etc.! Because it is relatively professional, the information is all from public materials on the Internet. I hope it can help you.
