JLP-40 Radar
Encyclopedia
The JLP-40 is a tactical air defense radar
designed to use with height finding radars such as the JLG-43 Radar
. It is similar in design to the Russian "Bar Lock
" series radar and may have been derived from it as part of the sale of the SA-2 system from the Former Soviet Union
in the early 1960s. It features the same arrangement of the two large scanners attached to front and ear sides of a rotating cabin that houses the transmitter/receivers.
scanner being illuminated by stacked horn feeds to generate families of multiple beams. There are five S-band transmitter/receivers and these are though to operate with the lower of the two antennas, while the L-band feeds illuminate the upper scanner array. An IFF
interrogator is incorporated in the system. Three PPI
displays are available, one azimuth/range display and two to four additional PPI. MTI is provided in the L - band modules.
The whole system is air transportable but requires considerable time and effort to assemble/disassemble. It is being produced by the Chengdu Jin Jiang Electronic System Engineering Company.
Radar
Radar is an object-detection system which uses radio waves to determine the range, altitude, direction, or speed of objects. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. The radar dish or antenna transmits pulses of radio...

JLG-43 Radar
The JLG-43 radar is a nodding height finding radar, a two-dimensional radar which only provides azimuth and height data and is normally paired with other air search radars which provides the range to complete the picture. It is very similar to the well-known Russian PRV-9 "Thin Skin" and PRV-11...

Operating Modes
The system operates in S-band and L-band, each parabolicParabolic antenna
A parabolic antenna is an antenna that uses a parabolic reflector, a curved surface with the cross-sectional shape of a parabola, to direct the radio waves. The most common form is shaped like a dish and is popularly called a dish antenna or parabolic dish...
