LW-R5 Surface Movement Radar

Overview:


Airport Surface Movement Radar LW_R5 airport surface movement radar can detect the moving and stationary targets with the active area of the airport (runways and taxiways) and monitor the targets in non-active area (apron, maintenance areas, etc.), with high range and azimuth resolution. It can provide more than 1Hz data rate, and fast, reliable and accurate detection on the movement of aircraft and motor vehicles on the airport surface. As an important device to enhance the efficiency of airport operations and traffic guidance safety, airport surface movement radar is widely used in a variety of large and complex airport and gradually extended to small and medium sized airports.


Airport surface movement radar can be used to help controllers know about the real-time position and movement of stationary and moving aircrafts and vehicles, issue the instructions to avoid traffic congestion and conflicts of aircraft/vehicle in the intersection, choose an appropriate route for aircrafts, and determine whether the runway is occupied; and to provide navigation information for vehicle, rescue vehicles in the case of an emergency.

LW-R5 has been trial running for 3 years at XinQiao airport of Hefei, and has obtained the first temporary license for Surface Movement radar of China civil aviation equipment in April 2017. And you are welcome to check our equipment at any time.

Technical Features:

1.Inverse cosecant square pattern antenna ensures effective detection in the airport surface area with the system tower at various heights ( 15m~110m ).

2.Full-solid state transmitter with easy installation and maintenance, low life-cycle costs.

3.Large dynamic receiver ensures all targets within the airport have a full range of effective monitoring.

4.Frequency diversity and frequency agility are adopted to reduce targets flicker and improve the detection probability and detection accuracy.

5.High data rate; the minimum speed of the antenna with 60 rev/min is required to realize information update in seconds.

6.The capabilities of target identification, high resolution and high positioning accuracy are realized. Real aperture imaging technique is adopted for imaging processing on targets. A large bandwidth signal and large size antenna are used to realize high resolution of range and azimuth.

7.High security, high reliability and strong environmental adaptability are realized to support all-day operations. It therefore is an important means of airport operation surveillance in low visibility situations.
