It has been known almost for the last 40 years that UHE cosmic ray
EAS emit pulsed radio emission in the LF-VLF range[1][2][3].We have been detecting
UHE cosmic ray air shower with the mini-array method[4][5]. A VLF receiver system is
setup near the mini-array hut[6].The received signals are observed using
DSO(Tektronix TDS-520A) and stored in PC via GPIB-PCI(NI-488.2) .Power spectral
density and inducing electric field strength are calculated by doing FFT on the
stored signal for different orientations of the receiver system. Received signals are
discriminated from the noise by observing simultaneous arrival of the VLF signals
with mini-array particle pulses, using coincidence unit.
