The SCR-25 Airport surface movement radar is designed to detect the moving and stationary targets within the active area of the airport and monitor the targets in non-active area, with high range and azimuth resolution.


Technical Features:
    ● Inverse cosecant square pattern antenna ensures effective detection from the tower of various heights.
    ● Full-solid state transmitter for easy installation and maintenance, and low life-cycle costs.
    ● Large dynamic receiver ensures a full range of effective monitoring for all kinds of targets.
    ● Frequency diversity and frequency agility improves the detection probability and accuracy.
    ● High data rate: the minimum speed of the antenna of 60rev/min is required to realize the airport information update in

    ● 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.
    ● High security, high reliability and strong environmental adaptability are realized to support all-day operations.
