FIELD: technical aids of fight against terrorism, applicable for prevention of explosion of transport facilities. SUBSTANCE: the detector uses a Doppler microwave sensor consists of an oscillator, receiving-indicating device and antenna, infralow-frequency seismic sensor of vertical oscillations of transport facility, controllable radio transmitter and a self-contained receiving device; the outputs of both sensors are coupled to a commutable logic circuit, whose output is connected to the controlling input of the radio transmitter, and the antenna of the Doppler sensor is made of coaxial cables with perforated ports operating on the principle of "outflow" waves. EFFECT: enhanced safety of transport facilities due to timely detection of mines installed on them. 3 dwg |
