[Scope of utility model registration request] An oscillator that oscillates radio waves, a transmitting antenna that emits these radio waves toward a target, a receiving antenna that receives reflected waves from the target, a mixer that mixes the received signal and the output of the oscillator, an amplifier that amplifies this output, and the output of this amplifier. A proximity fuze includes a detector that detects the output of the detector, a rise detector that detects the rise of the output of the detector and outputs a target detection signal, and a delay circuit that delays the output of this detector according to the approach speed, For the output of the above-mentioned wave detector, using the falling detector that detects the fall of the wave detector, and the outputs of the above-mentioned rising and falling detectors, interpolation is performed between these outputs according to the relative speed with the target, and the warhead is A proximity fuse characterized by having a timing adjustment circuit that outputs an optimal detonation signal.
