RADAR RELIABILITY TESTING
The careful control and recording of reliability
tests has proven vital for the development and
testing of complex radar systems in China
protected measurements in a frequency
range up to 80 kHz and with more than 120 dB
spurious-free dynamic range.
Following its strategy of always striving to
be a leader in the aerospace and defence
testing sector, m+p international has
integrated advanced control capabilities such
as notching/force limiting into its VibControl
software. Many safety features ensure
reliable closed-loop vibration control – from
pre-test checks to abort checking, notching

The 14th Institute of the China Electronics
Technology Group Corporation is the
birthplace of China’s radar industry. It has
developed many pieces of high-end radar
equipment and its products have been
exported to dozens of countries and regions.
The 14th Institute has been using m+p
international’s industry accepted VibControl
vibration control systems since 1996 to
conduct sophisticated radar reliability tests.
Reliability is an important index of radar performance. It
enables the effective verification of the design and is
mandatory to ensure full performance of radar systems.
Reliability tests can be used to detect faults. Engineers can
also use performance tests, functional tests or environmental
tests to find problems. These tests include random, sine,
shock, sine dwell and the shock response spectrum. They
determine the structural dynamic characteristics of the radar,
such as the resonant frequency, expose design and
manufacturing defects and verify functional integrity.
The vibration tests carried out on shakers and controlled by
m+p VibControl systems therefore play a key role in reliability
verification. The 14th Institute has more than 10 sets of m+p
VibControl software with m+p VibPilot and m+p VibRunner
acquisition hardware. m+p VibPilot is a compact, rugged
4/8-channel hardware platform. For higher channel counts,
m+p VibRunner hardware is the first choice. It can be used as
a desktop instrument or mounted into a 19in rack and
supports distributed measurements. Equipped with 24-bit
sigma-delta A/D converters and a sampling rate up to
204.8kHz, the m+p acquisition hardware allows for alias-
and controlled shutdown.
The radar’s reliability level is constantly
increased using these tests. Finally, the
expected value of mean time between failures
is reached and its operating cost is reduced.
In many radar reliability tests, m+p
international’s products played an important
role. The responsible technical engineers of
the 14th Institute expressed their satisfaction
with the test results and gave a high
evaluation of m+p international’s products. \\
