Purpose of the development: An important element in the protection of information from technical intelligence tool is monitoring the effectiveness of protection. This is especially important when working in the field of low-frequency magnetic fields (NPM), which have high penetrating power.

Recommended application field: Application area antennas AIM: - Performing all the functions of a large diameter loop antennas allow, thanks to the compact remote sensor to detect and localize the emission point sources of the magnetic field in almost any enclosed space, such as electromagnetic radiation (including information) of the individual components of a computer system and peripherals, hard fragments screen facilities, etc.; - In combination with special electronic converters can be used to detect hidden sources of secret information retrieval: video cameras and recorders; - High uniformity of frequency response enables use as an instrumental measurement tools; - In combination with the selective Microvoltmeter, spectrum analyzers, measurement receivers, are a powerful tool to detect and measure the intensity of the magnetic radiations of electronic devices; - In contrast to the common antenna with a diameter of 250 mm frame, can be covertly placed in certain points of the protected object and, when working together a spectrum analyzer, scanning receivers or other special meter signal a change in the operational electromagnetic environment (low-frequency magnetic fields) in a given point, both inside and on the perimeter of the protected object.

Advantages over analogues: Antennas AIM counterparts do not have.

The development stage readiness: Introduced in production

Description of the development:
()
When performing measurements with the loop antenna must be ensured: d> = D, where the d-distance from the radiation source to the antenna, and D - aperture antenna. Antenna with a small aperture provides more precise distance to the radiation source, which significantly from measurements in the near field. Compact antenna allows measurements close enough to the source. Point framework designed active antenna AIM series are characterized by high sensitivity and large dynamic range. New circuit solutions have reduced the diameter of the frame with 250 mm to 0.8 - 1 mm, respectively, to reduce the area of the antenna aperture is about 1000 times, making the loop antenna in a compact external probe. To cover the frequency range of 5 Hz ... 30 MHz (23 octaves) used three versions of antennas: AIM 0.005 AIM LF 200; AIM HF 0.1-30. The antennas have a certificate of metrological certification of State Standard of Ukraine.
