The Characteristics of LW-R25-K-1 Radar:

a) It adopts AESA, DBF, pulse compression, fully coherent pulse Doppler and other advanced techniques to search, find and measure the low-flying non-cooperative targets and provide targets’ distance, azimuth, altitude and Doppler velocity, which perfectly meets the needs of detecting and surveillance the aircraft in wind power plant.

b) The radar utilizes active electronically scanned array technique of two dimensions and microwave integrated transceiver components and gets rid of mechanical rotating device. Thus, it ensures high reliability.

c) The wide-band signal and pulse compressed technique improves the range resolution and ranging accuracy and reduces the echo intensity of clutter. High ranging accuracy achieves high-quality track correlation processing and greatly reduces the false alarm.

d) The range of ARW-001 Radar is large. It can simultaneously detect several small and medium wind power plants that are close, which reduces the quantity of radar and the cost.

e) The stable beam of electronically scanned radar helps suppress clutter. So it naturally has excellent clutter suppression performance.

f) The electronically scanning speed is fast, and the radar data rate is high, which helps classify targets and remove false targets through the track correlation processing and reduce the false alarm of radar warning.

g) The radar is installed at a distance beyond 5km from the wind power plant and automatically marks the position of the wind power plant. From the outside of the wind power plant, it can detect the various aircrafts which fly towards the wind power plant, so as to eliminate the influence of the rotating fan blade on target detecting, and reduce the false alarm of radar. The radar also effectively tracks and measures the aircraft which is flying over the wind power plant using the track correlation technique.

h) The system has online build-in test equipment, which can report the fault in real time.

i) The design of radar fully complies with the related design standards and the related requirements of EU.

LW R25-K-1 Radar is a measuring equipment with high cost-performance ratio, which can perfectly solve the problem of alarming air crafts in wind power plant.
