Description
The P-40 was the first high-mobility radar to enter into service with the then new tactical anti-aircraft forces of the Soviet armed forces.
The P-40 used the AT-T artillery tractor with tracked chassis, fitted with a 12-cylinder 4-stroke diesel engine with an output of 342 kW (465 hp) and producing a top speed of 55 km/h. The P-40 had a crew of 6 and a total weight of 35 tons, the radar being powered by a gas turbine running 400 Hz generator.
The radar uses an open frame truncated parabolic antenna with a stacked antenna feed. The radar antenna is mounted on the truck used to transport it giving excellent mobility, the radar capable of being folded for stowage during transit. Azimuth was determined by mechanical scanning while the angle of the target is determined from within which beam of the antenna stack the target is detected, the radar does not carry a secondary antenna for IFF.

Famous quotes containing the word description:
“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)
“Why does philosophy use concepts and why does faith use symbols if both try to express the same ultimate? The answer, of course, is that the relation to the ultimate is not the same in each case. The philosophical relation is in principle a detached description of the basic structure in which the ultimate manifests itself. The relation of faith is in principle an involved expression of concern about the meaning of the ultimate for the faithful.”
—Paul Tillich (1886–1965)
“The type of fig leaf which each culture employs to cover its social taboos offers a twofold description of its morality. It reveals that certain unacknowledged behavior exists and it suggests the form that such behavior takes.”
—Freda Adler (b. 1934)
