Description

Product Overview

The XH‑Ku‑576 Ku-Band 2D Active Phased Array Antenna is a high-performance radar antenna designed for medium-long range high-precision low-altitude security applications. It integrates radome, antenna array, beam-control power board, thermal dissipation module and rear housing into one unit, delivering inertia-free 2D electronic scanning in both azimuth and elevation. Its narrow beam characteristics provide superior angular accuracy and target resolution without mechanical rotation.

With highly integrated all-in-one design and built-in rear housing, it offers excellent environmental protection. It supports continuous receive, pulse transmit and TX-RX pulse switching modes, with integrated power amplification, spatial power combining and low-noise receiving. It is widely used in anti-UAV detection radars, medium-long range low-altitude surveillance and high-precision critical site security systems.

Key Advantages

Ku-Band Narrow Beam for High-Precision Detection
Operating at 15~17GHz Ku-band, with transmit beamwidth only 2.9° and receive beamwidth 3.5° at 16.2GHz. The narrow beam delivers higher angular resolution and accuracy, with EIRP ≥86dBm and G/T ≥3.5dB/K, suitable for accurate detection and stable tracking of low-altitude targets at medium and long ranges.
2D Active Electronic Scanning with Ultra-Fast Response
Covers ±45° in both azimuth and elevation. Beam switching time ≤40μs, typical TX-RX pulse switching time only 100ns, with excellent target acquisition and beam agility. It can quickly respond to multi-batch, highly maneuverable low-altitude targets, with no mechanical wear and long service life.
All-In-One Integrated Design for Easy Deployment
Integrates antenna array and rear housing in one unit, dimension 320mm×360mm×60mm, weight ≤18kg. The high integration greatly reduces system supporting work, enabling convenient installation and deployment, balancing performance and space adaptability.
Industrial Protection & Smart Thermal Management
IP67 ingress protection for the full unit with rear housing; cooling fan rated IP68. Built-in working status reporting, real-time temperature and current monitoring with adaptive fan speed control, adapting to harsh outdoor environments and ensuring long-term stable operation.
Flexible Multi-Mode Operation with High Reliability
Supports continuous receive, pulse transmit and TX-RX pulse switching modes. Based on mature active phased array architecture, it features high integration, lightweight, high performance and high reliability, flexibly compatible with radar systems of different architectures.
