Description

Product Overview

The XH‑256 X-Band 2D Active Phased Array Antenna is a highly integrated radar antenna featuring compact size and lightweight design. It integrates antenna array, beam steering power board and thermal dissipation module into one unit, delivering inertia-free 2D electronic scanning in both azimuth and elevation. It provides wide beam coverage without mechanical rotation, with fast response and high reliability.

With a compact 315mm square low-profile structure, weight under 3.5kg and power consumption as low as 235W, it significantly reduces deployment threshold and system supporting requirements. It can be flexibly deployed in portable stations, vehicle-mounted systems and small platforms, and is widely used in anti-UAV detection radars, mobile low-altitude surveillance and temporary perimeter security.

Key Advantages

Ultra-Light & Compact for Flexible Deployment
Dimension 315mm×315mm×65mm, weight ≤3.5kg. The ultra-thin compact structure greatly reduces installation space requirements, and is compatible with portable setup, vehicle-mounted mobility and small platform integration, improving installation and transportation efficiency.
2D Active Electronic Scanning with Ultra-Fast Response
Covers ±45° in both azimuth and elevation. Beam switching time ≤70μs, typical TX-RX pulse switching time only 150ns, enabling rapid acquisition and tracking of low-altitude slow targets, supporting multi-target scenarios. No mechanical wear ensures longer service life.
Stable RF Performance with Controllable Sidelobes
EIRP ≥80dBm, total receive gain ≥55dB, G/T ≥0.5dB/K. Receive sidelobe level ≤-22dB, transmit sidelobe level ≤-12dB, with adjustable weighting depth. It delivers good detection accuracy and anti-interference capability to meet the performance requirements of compact radar systems.
Industrial Protection & Smart Thermal Management
IP67 ingress protection for the full unit when paired 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.
Low Power Consumption & Multi-Mode Flexibility
Total power consumption ≤235W @ 20% transmit duty cycle, greatly reducing power supply requirements. Supports continuous receive, pulse transmit and TX-RX pulse switching modes, with integrated power amplification, spatial power combining and low-noise reception, flexibly compatible with radar systems of different architectures.
