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:
“I was here first introduced to Joe.... He was a good-looking Indian, twenty-four years old, apparently of unmixed blood, short and stout, with a broad face and reddish complexion, and eyes, methinks, narrower and more turned up at the outer corners than ours, answering to the description of his race. Besides his underclothing, he wore a red flannel shirt, woolen pants, and a black Kossuth hat, the ordinary dress of the lumberman, and, to a considerable extent, of the Penobscot Indian.”
—Henry David Thoreau (1817–1862)
“Once a child has demonstrated his capacity for independent functioning in any area, his lapses into dependent behavior, even though temporary, make the mother feel that she is being taken advantage of....What only yesterday was a description of the child’s stage in life has become an indictment, a judgment.”
—Elaine Heffner (20th century)
“An intentional object is given by a word or a phrase which gives a description under which.”
—Gertrude Elizabeth Margaret Anscombe (b. 1919)
