A self-modulating, remote, moving target detector for intrusion alarms, vehicle detection, and remote speed and distance measurement that includes a remote continuous wave radar transceiver that is used to detect moving targets. Small deflections along an arc of bending create a desirable signal level via mechanical amplification. The coil filler includes an insulating resin permeating the coil. The stock web is subjected to up and down dewatering creating separately formed layers to reduce fiber-to-fiber bonding.
