Communication method for mines of a land minefield and mines for working out thereof

摘要

The system consist of mines (2) with active induction sensors, generators and signal processors, controlled by fixed or mobile transmitters (3,4). A signal fed to the mines by one of the transmitters is picked up by at least one mine and relayed by it at least once to its neighbouring mines, and so on. The frequency for communicating signals between mines is different from the frequency they use for target detection and is selected at random from the frequencies available, and the signals between the transmitter and the mines and/or between mines are encrypted.
