Low altitude targets perform as greater threats for the air defense system in war. Modern aircrafts such as fighters, cruise missiles, unmanned aerial vehicles and armed helicopters have the capability to break through defense. As critical parts of air surveillance equipments, radars play crucial roles to attack low altitude targets, and they require stronger surveillance capability in more complex combat environments with more targets. Nowadays, there are more kinds of low altitude radars on the international market, which contribute greatly to strengthening low altitude defense.
Key Technical Features of Low Altitude Surveillance Radar
Key technical features of low altitude surveillance radar are new signal processing technology, high-performance low sidelobe antenna, strong mobility and easy deployment.
New Signal Processing Technology
In order to strengthen anti-disturbance capability, low altitude surveillance radars often adopt broadband signals, frequency agility and full coherence. Advanced MTI technology is used to confront complex hybrid wave environments for radar, ensuring to capture effective low altitude targets.
High-performance Low Sidelobe Antenna
High-frequency spectral purity and low sidelobe antenna should be used to ensure detection performance and anti-hybrid-wave capability. It can also solve the problem of complex topography in low detection height.
Strong Mobility and Easy Deployment
The location of low altitude surveillance radar is often not fixed, which requires strong mobility for different working environments and various vehicles. Easy field deployment is also needed as operation time is strictly restricted. With the massive adoption of lifting up antennas, the radar should be equipped with antennas of reliable retractable structure and speed.
