Pagination or Media Count:
A dual mode sensor having a seismic channel and an RF channel with a logic circuit recognizing both channels. The seismic channel detects disturbances with a geophone and determines the spacing and the density of the impulses while the RF channel radiates electromagnetic energy and detects impedance changes in the oscillator circuit driving the antenna when the target is in the field. The rates of changing impedances and their thresholds are determined. Author
