Theseus-21

The device is developed for protection of VIPs, convoys and high-security objects against threats of possible terroristic acts when explosive devices with radio controlled fuses may be used for it.

The device also can be used for jamming cellular, trunked radio and other types of communication links on big squares, stadiums, transportation terminals, counter measures against UAVs (jamming their control lines) and so on.

Frequency range 20…3000 (option up to 6000) MHz
Principle of operation

The device is built on new principle with application of ultra wideband processing in optical range of all modulated signals in any format in the air. It allows to skip scanning at frequency operating range wider than 7 octaves and accordingly it seriously decreases the response time of jamming against terrorist radio signals for bomb blasting. During maximum 0.5 microseconds, the special processor analyses all received signals within its operating frequency range and forms jamming signals. Internal structure of jamming signal is similar to the structure of received useful signal in which the specially formed distortions are added.

Such way of forming jamming signal allows the device efficient operation with any number of radio sources and with any modes of radio transmitting such as, for instance, frequency hopping mode.
