ASKM 5/8–-0.9/18 circular antenna array 0.9–18 GHz (five frequency sets)

Product components:

• Antenna elements;
• Units of the antenna-feeder path;
• Radome;
• Chassis for installing instrumentmodules.

ASKM 5/8-0.9/18 annular equispaced antenna array with 5 sets of frequencies is designed to receive signals from radio equipment with linear and circular polarization in the frequency range of 0.9 to 18 GHz in a circular azimuth coverage;

To increase the energy potential and direction finding accuracy, the operating range of the antenna system is divided into 5 frequency sets: 0.9–2 GHz, 2–4 GHz, 48 GHz, 8–12 GHz, 12–18 GHz;

Recommended to be used as a direction-finding receiving antenna system of search and searchless robotic systems;

The antenna system is made in the form of a five-tier annular antenna array;

All-round field of view (360°) is ensured:

• in the range of 0.9 to 2 GHz, by АS8.33 spiral antennas (8 pcs.);
• in the range of 2 to 4 GHz, by cophasal antenna array (8 pcs.) based on AS4.89 log-periodic antennas (2 pcs.);
• in the range of 4 to 8 GHz, by cophasal antenna array (8 pcs.) based on AS4.89 log-periodic antennas (2 pcs.);
• in the range of 8 to 12 GHz, by AS6.56.3 broadband antennas (8 pcs.);
• — in the range of 12 to 18 GHz, by AS6.56.4 broadband antennas (8 pcs.)

Antenna system provides simultaneous spatial scanning in 2 or more independent channels;

Antenna system design provides for the installation of 3U instrument modules;

The product may be equipped with multi-channel frequency converters, as required by the customer.
