1 Product Introduction

X-band civil low-altitude three-coordinate surveillance radar is an all-solid-state fully coherent active phased array three-coordinate low-altitude surveillance radar. It is mainly used to search and track low-altitude low-speed small targets such as UAVs in low-altitude airspace (below 1 km), and to output the distance, orientation, height and velocity information of targets in real-time, so as to form the three-dimensional motion situation of low-altitude targets. Provide effective information support for low altitude control and interception strike system. It has high reliability and automatic target detection ability to monitor non-cooperative targets and high-threat targets around the key areas.

2 Application Area

a) Civil Air Defense Surveillance

  This radar is applied to monitor general aviation manned aircraft and large unmanned aerial vehicles, prevent general aviation and terrorists from using drones to carry out attacks, and provide effective surveillance means for civil air defense departments in low-altitude airspace

b)Low Altitude Airspace Surveillance

  Radar can effectively monitor payload-capable drones that can pose a threat to key defensive targets, and can be used on defensive air surveillance in places such as island reefs, nuclear power plants, oil depots, prisons, airports, large conference venues, important government agencies, military units, border, etc.

c)Navigation Airport Proximity Monitoring

  The airspace coverage of this radar is consistent with the flight area of general aviation airport, and the radar does not need to be equipped with transponder, so it is suitable to be used as a small general aviation airport aircraft for proximity surveillance.

3 Main Features

a) Low altitude, Slow speed, Small Target Monitoring Capability

With advanced active phased array system and high data update rate, it provides excellent low altitude, slow speed and small target monitoring capability. This product has excellent detection performance for consumer UAV, and the monitoring distance for Dajiang Mavic Pro miniature four-rotor UAV is more than 5 km.  

b) Advanced System, Flexible Working Mode and Ability of Target Height


The radar adopts the advanced receiving and transmitting digital beamforming system in the international market, which has the advantages of high utilization of radar resources and various modes of operation, flexible pointing and controllable beam direction, strong adaptability to the position, and can meet the needs of different tasks. The receiver adopts all-digital beamforming technology and has the capability of altitude measurement of non-cooperative targets.

c) High Integration, Low Cost, Miniaturization, High Reliability

The radar equipment is integrated into the antenna or turntable except for the back-end processing and display equipment. It has the advantages of high integration, low cost, low loss, low infrastructure requirement on the installation site, convenient installation and high reliability, etc.

4 Product Structure and Deployment

The antenna assembly of X-band civil low altitude 3-axis surveillance radar weighs about 50 kg and the turntable weight is about 30 kg. This product, with high deployment flexibility, can be installed on the top of the building or on vehicle platform (figure 1).

Figure 2  Flight Monitoring Diagram

The X-band civil low altitude 3D surveillance radar is fully satisfied with the surveillance of civil aircraft below 3km. Figure2 shows the monitoring effect of this radar outfield position deployed near Hefei Xinqiao Airport to the entry-exit aircraft. This radar can accurately monitor the flight trajectory and altitude of the aircraft.

X-band civil low altitude 3D surveillance radar also satisfies the surveillance of UAV, and its monitoring range depends on the size of UAV. Taking the UAV produced by Dajiang Company, which has 70% market share of global commercial UAV, as the experimental object, the monitoring distance of the larger Mavic Pro miniature four-rotor UAV is more than 5km, and the screenshot of the surveillance picture is shown in Figure4.
