摘要：
In this paper we describe two versions of a compact broadband ferrite based induction magnetometer system which span an operating bandwidth from 1 mHz to 1 MHz. In order to produce this compact system it was necessary to consider both the design of the pick up coils and the signal processing electronics. Here, we present an alternative to the traditional analogue integrator technique and conclude that this leads to significant advantages in bandwidth, long term stability and weight of the coils.
