SF-X60 Low-Altitude Early-Warning Radar
Overview

The LT-X60 phased-array UAV surveillance radar is a key low-altitude monitoring system featuring unattended operation, high reliability, low cost, and a phased-array architecture.

It is designed for low-altitude (0 m – 3000 m), small-RCS (0.01–10 m²), and slow-speed (3 km/h – 400 km/h) targets.

A single radar unit can detect and locate low-altitude flying targets within a near-field range of 0.1–50 km.

When networked, multiple radar nodes can provide low-altitude surveillance of critical areas such as urban regions, borders, and air corridors.

By deploying a network of phased-array radars, the system can perform real-time detection, tracking, and localization of multiple targets across a wide area.

Compared with traditional low-altitude monitoring radar solutions, this system offers lower cost, smaller size, easier deployment, and higher reliability.

Each radar node can be co-located with a mobile communication base station, utilizing the station’s power supply and cooling system, while exchanging radar detection data through the base station’s fiber-optic network interface.

The primary function of this radar is to provide networked coverage of key regions and to perform search and surveillance of low-altitude targets within the 0–3000 m altitude layer.

Main Features

This system is capable of all-weather operation and offers long detection range, accurate real-time positioning, strong target acquisition capability, and rapid, precise interference response.

Key features include:

  • Phased-array architecture with high sensitivity and stable performance.
