Description

Product Overview

The XH‑Ku‑256 Ku-Band 2D Active Phased Array Antenna is an ultra-lightweight radar antenna designed for portable and distributed low-altitude security scenarios. It integrates radome, antenna array, beam-control 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, balancing basic detection performance and extreme deployment flexibility.

With compact design, weight under 3kg and power consumption as low as 260W, it significantly reduces deployment threshold and power supply requirements. It can be set up and transported by a single person, and is flexibly compatible with man-portable devices, vehicle-mounted platforms, distributed networking nodes and temporary perimeter security. It is widely used in anti-UAV detection radars and mobile low-altitude surveillance systems.

Key Advantages

Ultra-Lightweight for Single-Person Portable Deployment
Dimension 220mm×310mm×54mm, compact size and weight ≤3kg, making it one of the most lightweight models in the series. It can be quickly set up and flexibly relocated by a single person, greatly reducing installation and transportation costs, perfectly suitable for man-portable, vehicle-mounted and temporary deployment scenarios.
Ultra-Fast Beam Agility for Multi-Target Response
Covers ±45° in both azimuth and elevation. Beam switching time ≤30μs, typical TX-RX pulse switching time only 100ns, enabling fast target acquisition and beam scheduling for multi-batch low-altitude targets. No mechanical rotating structure ensures zero wear and long service life.
Stable RF Performance with Adjustable Sidelobes
EIRP ≥78dBm, total receive gain ≥55dB, G/T ≥-2dB/K. Receive sidelobe level ≤-22dB, transmit sidelobe level ≤-12dB, with adjustable weighting depth. It delivers good detection accuracy and anti-interference capability, meeting the requirements of short-to-medium range low-altitude target detection.
Ultra-Low Power Consumption for Wide Adaptability
Total power consumption ≤260W @ 20% transmit duty cycle, with maximum transmit duty cycle up to 25%. The ultra-low power feature greatly reduces power supply requirements, especially suitable for battery-powered portable devices and low-power supporting scenarios. Supports continuous receive, pulse transmit and TX-RX pulse switching modes, compatible with various lightweight radar systems.
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.
