has achieved a high degree of autonomy in the development and engineering of
missiles. It has state-of-the-art world class facilities for designing,
developing, testing and building a range of missiles. Following are some of
the facilities available with DRDO:
EMI/EMC Compatibility Test Facility
A state-of-the-art electromagnetic interference and
electromagnetic compatibility (EMI/EMC) test facility has been set up by
Automatic EMI susceptibility
measuring system, which can generate 200 V/m field in the frequency range of
10 kHz to 40 GHz; automatic EMI data collection system, which can measure
emissions in the frequency range of 30 Hz to 40 GHz; and human and vehicular
electrostatic discharge testing facility have also been established.
Antenna Fabrication Facility
Antenna fabrication facility has
provision for developing precision microwave planar array antennas at Ku-
and Ka-band involving slots of minimum width of 0.5 mm with accuracy of ±10
Slotted planar array
development of the missile system is an exciting and challenging process.
Successful flight-testing is a demonstration of the successful completion of
design and development process. However, before the missile is committed to
flight trials, it is ground flight tested on the hardware-in-the-loop
simulation (HILS) platform.
Missile motion simulator
On the HILS platform, the
actual sub-systems along with flight software are tested on the trajectory
of the missile from liftoff to impact. DRDO has developed HILS test beds for
various types of missiles.
Radar Cross-Section & Microwave Imaging Facility
DRDO has established a radar cross-section measurement facility to
cater for widespread technical applications in its ongoing and futuristic
programmes. A state-of-the-art system operating at W-band has been developed
and integrated in the existing compact antenna test range as MWS (millimeter
wave scattering) project to perform measurements on ‘all metal-scaled
Model under evaluation
Critical areas of research
like calibration targets, measurement procedure, error modelling along with
the indigenous development of low observable RCS pylon has seen the
technology to come up to the level to locate low observable aircraft models
and their 2-D images in both CW and pulsed mode of operation. This gives
insight not only in the gross scattering behaviour of the geometry under
test but also the distribution of prominent scattering center (hot spots) on
The capability of the test facility has been upgraded to perform precise
measurements on RCS reduction materials.
Radome Calibration Test Facility
A state-of-the-art test facility for calibrating missile radome has been
established with very high degree of precision by DRDO. The most important
constraint of simulating antenna angle inside the seeker has been achieved
by integrating an indigenously developed antenna positioner for generating
precise relative angles.
Configured range for radome calibration with additional
The complete axes alignment
technique using lasers, RF and motion calibration along with measurement
procedure has been evolved for measurement of radome parameters for all
An automated (online) acquisition and analysis software has been developed
in-house to cater for wide range of sources and receivers, namely Scientific
Atlanta 1783 and 1797. Further, post acquisition data processing algorithm
has been developed to increase the measurement repeatability within ± 0.50.
The system is fully operational.
Environment Testing Facility
A state-of-the-art environment test facility of international standard has
been established for dynamic and climatic environment.
Dynamic test facility
Experimental model testing
and analysis, airborne noise measurement and analysis, and dynamic balancing
of rocket facility have also been set up by DRDO.
Multipoint Excitation Testing for Model Analysis
A state-of-the-art multipoint excitation testing for model analysis has been
established for vibro acoustic, pyro-shock, and kinetic heating tests. A
number of test like high altitude simulation, rain and icing simulation,
salt corrosion, low and high temperature, combined environment, and tropical
exposure can be done in the facilities.
Pendulum Shock Testing Machine
Pendulum shock testing machine
machine is a device, which allows modification of the velocity over a short
period of time. Pendulum shock machine is an impact type machine where
impact velocity is obtained by gravity. DRDO has developed a cost-effective,
maintenance free pendulum shock machine to test pay loads. The maximum UUT
size is 500 mm x 500 mm x 500 mm.
