Abstract

A pulse Doppler proximity sensor uses a plurality of stepped output radio signals for accurately determining the relative range between the proximity sensor and an object. A dual modulation technique is employed which incorporates a pulse modulation arrangement and a carrier frequency modulation arrangement to detect the necessary range accurately from the plurality of output radio signals. The proximity sensor processes in parallel each of the plurality of output radio signals returned from the object. A binary comparison is made and the comparison is integrated over time to prevent false alarms. The pulse Doppler proximity sensor is particularly useful in fuzing arrangements for a munition in which a number of range settings are desired.
