Product Description

 

Product Description

The antenna array works in conjunction with a five-channel direction-finding receiver to perform radio direction-finding.

This 9-element antenna array operates across a wide frequency range of 500MHz to 3GHz, making it suitable for diverse applications in communications and radar systems. The array consists of nine spatially distributed antenna elements, enabling high-accuracy Direction of Arrival (DOA) estimation through advanced signal processing techniques such as phase comparison, amplitude comparison, or super-resolution algorithms (e.g., MUSIC, ESPRIT).

The system supports five independent RF channels, allowing simultaneous multi-signal processing and enhanced interference mitigation. Its broadband coverage ensures compatibility with various signals. The array's compact and optimized geometry minimizes mutual coupling while maintaining high gain and directional sensitivity.

Designed for both fixed and mobile deployments, this DF antenna array is ideal for spectrum monitoring, signal intelligence (SIGINT), and electronic support measures (ESM). Its real-time processing capability enables rapid detection and tracking of emitters in dynamic environments. The system can be integrated with software-defined radio (SDR) backends or embedded DSP units for adaptive beamforming and signal analysis.

This high-performance solution balances wideband operation, multi-channel flexibility, and precision direction-finding, making it a versatile tool for aerospace, and civilian spectrum management applications.
