Four single component magnetic field sensors are used to make up of a detection device that has dual-magnetic field gradient inputs as reference.The four single component sensors compose three magnetic field gradient sensors with one as signal sensor
the other as noise sensors.Let the output of signal sensor be the original input and those of noise sensors as reference inputs
then noise caused by the change of orientation of magnetic field sensor relative to geomagnetism orientation can be eliminated efficiently
as well as bow wave due to carrier movement.Practical application shows that the detection device presented in has good technic property
high sensitivity with low false alarm probability.
