Description
The systems were developed by the Institute of Metal Science and are based around electronic fuzes with broadly similar functionality. The fuzes use two sensors. The first, an acoustic sensor, arms the mine as a helicopter approaches. The second sensor is a radar sensor, which locates the target and triggers the mine at the optimal point. The mines all use a number of large Misznay Schardin effect warheads to project large numbers of fragments to an effective range of around 200 meters. Jane's Mines and Mine Clearance speculates that IFF could be integrated into the fuse circuit to discriminate against friendly aircraft.

Famous quotes containing the word description:
“The Sage of Toronto ... spent several decades marveling at the numerous freedoms created by a “global village” instantly and effortlessly accessible to all. Villages, unlike towns, have always been ruled by conformism, isolation, petty surveillance, boredom and repetitive malicious gossip about the same families. Which is a precise enough description of the global spectacle’s present vulgarity.”
—Guy Debord (b. 1931)
“To give an accurate description of what has never occurred is not merely the proper occupation of the historian, but the inalienable privilege of any man of parts and culture.”
—Oscar Wilde (1854–1900)
“As they are not seen on their way down the streams, it is thought by fishermen that they never return, but waste away and die, clinging to rocks and stumps of trees for an indefinite period; a tragic feature in the scenery of the river bottoms worthy to be remembered with Shakespeare’s description of the sea-floor.”
—Henry David Thoreau (1817–1862)
