Aiming at problem that in muzzle blast wave field test

large numbers of measuring points are relatively decentralized

wireless sensor networks（ WSNs） technology is applied to test

which not only improves electrical flexibility of test system

but also provides an unified time base for the whole testing system. Intelligent design of power management module of wireless module and working process of WSNs are mainly introduced

and calibration test based on shock tube and field gun measured test are held to test wireless synchronization of system. Experimental results show that applying WSNs technology to muzzle blast wave test can make the equipment operation more simple

improve mobility and efficiency of testing.
