Proximity fuze using Doppler effect with phase comparator

The fuze has a function generator (FG) which produces a time-dependent DC output corresp. to the declining missile velocity with any necessary correction. It adjusts a voltage-controlled oscillator (VCC) whose output is applied together with the radial relative velocity Doppler signal to a phase com...

Beschreibung
Zusammenfassung:	The fuze has a function generator (FG) which produces a time-dependent DC output corresp. to the declining missile velocity with any necessary correction. It adjusts a voltage-controlled oscillator (VCC) whose output is applied together with the radial relative velocity Doppler signal to a phase comparator (PD). The VCC supplies the comparison frequency required for the instant of detonation so that the phase comparator triggers the detonation switch when the Doppler frequency attains the comparison value.
