ABSTRACT:
This invention relates to a proximity sensing apparatus for energizing a control circuit whenever the distance between two objects moving relative to one another at an angle other than 180.degree. becomes a minimum, and more particularly, relates to a proximity sensing apparatus operating on the zero doppler principle for energizing a detonation circuit in a missile whenever said missile passes closest to a target.
