FIELD: blasting operations, physics. ^ SUBSTANCE: radio proximity fuse parameter measurement unit incorporates a transceiver antenna system, high-frequency amplifiers, a driving oscillator, a noise generator, a mixer, a modulator and sound-frequency generator. Note that the noise generator output is wired to the driving oscillator input, the said driving oscillator output being connected, via the modulator, to the mixer input. The sound-frequency generator is connected directly to the modulator input, while the receiving antenna output is connected thereto via the high-frequency amplifier. ^ EFFECT: fuse parameter measurement increased accuracy. ^ 1 dwg |
