An improved strain responsive line sensor detection system which is selectively sensitive to motion of a mass on a surface. In a line sensor having a uniform thin film plated wire, the sensitivity of the line sensor falls off with distance of the intrusion from the source end of the line where are connected the high frequency drive and the processor electronics. In this invention, the angle of magnetization skew of the thin film plated wire is made monotonically non-uniform along its length whereby the sensitivity of the wire along its length changes to provide compensation for the losses in the plated wire thereby making it possible to extend the length of a thin film line sensor.
