一种应用于磁源目标识别的大量程低噪声矢量磁强计
A Large Range and Low Noise Vector Magnetometer for Magnetic Target Recognition
摘要
Abstract
According to the need for large range,low noise vector magnetic field detection systems in magnetic source target recognition,a vector magnetometer based on magnetoresistive sensor HMC1021Z is proposed.Through experimental testing,the magnetic field detection range of the vector magnetometer can be as high as±6×105 nT.At the same time,it has a high linearity,and the nonlinear error is≤5.6‱.Root mean square(RMS)noise is 1.2611 nT and power spectral density(PSD)noise is 0.8 nT/√Hz@1 Hz.-3 dB bandwidth is DC to 8 Hz.All these characteristics make the proposed vector magnetometer meet the requirements of magnetic field detection with large range and low noise in magnetic target recognition applications.关键词
