omnidirectional intensity
1.Through analyse PHS network lose principle of words, draw to it lays to be to is it interfere , reduce lose origin of what to reduce rationally base station, through adjust some base station position , inclination under the aerial , change omnidirectional antenna beam antenna ,etc. among project, combine and adjust relevant parameters, to improve the intensity of signal that TCH interfere the area or reduce the background noise, thus solved and upgoed and fallen TCH caused to interfere well.
2.The vector hydrophone is combined by traditional and omnidirectional pressure hydrophone and independent on frequency band and natural dipole particle velocity hydrophone, which co-locating and simultaneously measures pressure and particle velocity, so acoustic intensity vector is obtained using those information, which consists of intensity and direction of sources.
