What is the development trend of radar technology?

It is manifested in the development of radar antennas from mechanical scanning to phased array electronic scanning, the development of passive phased arrays to active phased arrays and digital array radars, and the development of digital beamforming technology. Vacuum tube devices are gradually being replaced by solid-state devices. Solid-state devices have better performance and lower cost, and can realize microwave monolithic integrated circuits, system-on-chip, and on-chip radar.


Information theory is applied in radar, enabling radar systems to use more complex algorithms and signals, and the ability to adapt to the target and environment. The operating frequency, bandwidth and resolution of the radar are all increasing. The larger working bandwidth enables the radar to achieve higher resolution. The multi-band, shared spectrum enables the radar to work simultaneously in multiple bands. The high operating frequency makes the radar more Miniaturization enables installation on a smaller platform. Radar is constantly evolving in both military and civilian technologies.


Thanks to the ever-decreasing cost, size and power, the array radar antenna has higher integration and the number of array elements is increasing. The conformal array is another development direction of the phased array antenna.
