System for detection and location of human distress ON WATER

摘要

A system for detection and location of the person in distress in the water, comprising a life jacket worn by the person and having two light sources, one of which is located in the thoracic region of the lifejacket, and other - in zaspinnoy its domain, two miniature transmitter with transmit antennas one of which is located in the thoracic region of the lifejacket, and other - in its region zaspinnoy, a current source, two circuit breaker, two communicating hermetically sealed container, each of which separated from the environment membrane, with one of the sealed containers located in the thoracic region of the lifejacket, and other - in zaspinnoy its domain, the membrane of each container associated with isolating its corresponding light source circuit by the arm and both the light source and transmitters via breakers connected in parallel with the current source and the equipment installed on board the helicopter and consisting of one of the two direction-finding and measuring channels, the measuring channel consists of n consequently included reception antenna, the fourth narrowband filter, the first phase inverter, a first adder, a second input coupled to an output of the receiving antenna, the first bandpass filter, second phase inverter, a second adder, a second input coupled to an output of the first adder, the second bandpass filter, the third phase inverter, third adder, a second input coupled to an output of the second adder, the first mixer, a second input coupled to the first output of the first oscillator, a first Further, regulation
