This stage, the basic orientation of the development of radar technology to improve radar performance and expansion capabilities to meet the economic, social and national security needs. For example, mention Gao radar sensitivity (improved detection and suppression technology background interference), and increase the effective power aperture product of the technology, can increase the detection range or better detection of small targets (including “stealth” target \ the development of more general pulse Le technology, benefit from the strong ground clutter to detect low-flying targets and extract the target parameters; for severe convective weather storm zone three-dimensional structure, only by the Doppler technique can be explored. of the rapidly developing synthetic aperture radar technology, no longer observing the object as a “point” target, Jin measure HP 4210s battery it’s position and movement parameter; Er Shi Chang Jing by Huo De objectives and the image, measured objectives of the other Tezhengcenliang, Ru shape, size, fine Jie Gou Shen Zhi Wu Li properties to extend the range of radar measurement of target parameters. synthetic aperture radar technology has become the first professional application of a new radar features 11 images, and applied to different radar. more progress in radar technology to improve the radar target detection accuracy, resolution, anti-jamming capability, target identification capability.

Advances in radar technology, ranging from system design to the basic component parts of a whole range of progress, but the main radar system technology, microwave antenna, high power transmission technology, high performance receivers and signal processing technology and high-speed data processing technology. For example, in the antenna, since the pulse Doppler radar and other requirements with the high gain antenna and low sidelobe, so Waveguide Slot Array Antenna has been developed rapidly, and its sidelobe levels are better than one 40DB traveling wave slot array antenna array has been developed was successful and practical application; However, the antenna of the most remarkable development is the phased array antenna technology, has developed and applied a passive phased array (only the antenna array access in each unit of a phase shifter, and transmitter and receiver is still centralized), semi-active phased array (except for each antenna array element access to a phase shifter, the will all the cell groups, each group has had a transmitter Dell XPS 1340 battery and receiver end of class front-end) and the Active Phased Array <Array Each unit has a transmitter receiver component of a T / R components). In the transmitter, the operating frequency at 4GHz below (mainly P, L and S band) and solid-state transmitter (usually silicon microwave bipolar power transistors> has matured and gained practical application, to improve the performance of radar systems and reliability. In the receiver, the IF digital technology and high-stability frequency synthesis technology has been widely used, direct digital frequency synthesis (DDS) technology and to the FM receiver is also broadband access to the application.

Radar operating frequency from the microwave band to the ends of extensions: high-end to the millimeter wave and laser direction, low-end to short-wave direction. Have been a millimeter wave radar, laser radar and short-wave OTH radar, to meet some special requirements.
