System for automatic recording of missiles landing in target area has coil consisting of at least one winding bounding target area, measurement elements detecting change in coil inductance

摘要

The system has at least one alternating field source for generating an alternating electromagnetic field and measurement elements for measuring a physical parameter depending on the interaction between the missile and field. The source is an electrical oscillator circuit with a coil consisting of at least one winding bounding the target area and the measurement elements detect the change in at least one parameter dependent on the coil inductance.
