The reflector of DMRL-C with a surface diameter 4.6m,
weights 244 kg (NB: an aluminum reflector of the similar sizes weights 460
kg!), it is completely made of composite materials on the basis of fiberglass-plastic.
One of the main advantages of DMRL-C in comparison
with a composite reflector in comparison with similar radars made of metal is
its small weight which allows to optimize the design of the rotary device, and
to increase service life of driving mechanisms. Besides, composite materials have
smaller temperature expansions factors and increase invariance of the antenna device
signal of the radar which considerably increases accuracy of measurements, at
the same time reflectors made of composite materials have the same strength
characteristics as similar reflectors made of metal.
Production accuracy of the reflector' s surface is
controlled by a 3D scanner and its RMS-error is less than 1mm from theoretical
surface along the entire surface area of a reflector. Allowable temperatures
range is from -50°C to +50°C.
In comparison with foreign analogs DMRL-C is
competitive when it comes to its production cost and performance data.
