PURPOSE: To restrict explosion of a warhead until encountering a flying target, by a method wherein an arming signal generated in response to a voltage of a probe as a missile approaches into an electric field inherently associated with the flying target is applied to a first detecting part to detonate the warhead. CONSTITUTION: Current proportional to the voltage of a probe 24 to be generated as a missile approaches an electric field of a target is converted to a voltage of a signal and amplified to be supplied to a microprocessor 30. When an attack target is captured, the microprocessor 30 outputs an arming signal to make a fuse 36 of a warhead of the missile ready for operation. An RF receiver 38 of an active type proximity searching part transmits a signal via a radar antenna 26 and receives a signal returned from the target 10 to generate a signal for triggering the fuse by a microprocessor 40, which is applied to the other output side of a coincidence gate 34. But a gate 34 will not operate until the missile enters a range of a target detecting distance of a passive type detecting part 29, thereby preventing earlier detonation of the fuser 36.

PURPOSE: To shoot down an attacking target with the maximum damage, by a method wherein it is judged whether the initial slope of a waveform of a probe current increases or not within a set range of a value of a characteristic slope of the attacking target, and, when the reference is met, a warhead is detonated by the first zero current crossing made in the waveform of the signal. CONSTITUTION: Current of a probe short circuiting circuit flows in the form of a slope Part 38a increasing on the initial negative side. As a distance to a target is shorter, the waveform of the current of the short circuiting circuit is rapidly inverted in slope to cause a crossing of the zero level at a point 38b and further rises up to a peak 38c. As the polarity of the peak 38c is opposite to the polarity of the initial current, the peak 38c is a point which coincides with a position where a missile approaches the target the most on a target proximity effective destruction flying path 16a. A microprocessor 34 converts an amplified analog probe signal to a digital signal to enable the determination of the timing for the detonation of a fuser and the explosion of a warhead when the missile is precisely flying over the target proximity effective destruction flying path 16a.

The transmitter for an A.C. capacitance proximity fuze consists of an A.C.enerator whose output is directly connected to the transmitter probes of an A.C. capacitance fuze. The A.C. generator may be either a wind driven alternator or a fluid oscillator power supply driven by the ram pressure of the air. This arrangement eliminates the need for a separate oscillator as the power supply is now also the transmitter.
