Claims

[Scope of utility model registration request]

In a radar device that generates high-frequency pulse power, amplifies the power of the high-frequency pulse power with a cross-field amplifier tube, and radiates the high-frequency pulse power to the outside from an antenna as a transmission radio wave, the high-frequency pulse power generation section that generates high-frequency pulse power, and the high-frequency pulse power generator that generates high-frequency pulse power, and a trigger generator that applies a trigger to a power generation section; a cross-field amplifier tube power amplification section that amplifies the power of the high-frequency pulse power; and an antenna that radiates the power-amplified high-frequency pulse high power to the outside as a transmission radio wave; A coupler that extracts a portion of the high-frequency pulse power, a detector that outputs a pulse corresponding to the output level of the high-frequency pulse power generator, and a minimum reference level for a portion of the high-frequency pulse power extracted from the coupler. a reference level setter; a comparator that compares and detects the output amplitude level of the pulse output obtained from the detector and the lowest reference level set by the reference level setter and outputs a pulse when the output amplitude level is higher than the reference level;
A delay line that sets the pulse output from the above comparator to the required timing, a one-shot multivibrator that sets the output from the above-mentioned delay line to the required pulse width, and an output pulse from the one-shot multivibrator. A radar device comprising: a high-voltage pulse generation section that applies a high-voltage pulse to the cross-field amplifier tube power amplification section.
