部とを具備してなることを特徴とする検出装置。 A frequency discriminator that converts the frequency of the Doppler signal received by the target into a voltage signal proportional to the frequency, a converter that converts the output signal of the frequency discriminator to a digital signal proportional to the frequency discriminator, and outputs the digital signal, and the frequency discriminator. A differentiator detects a sudden change in the Doppler frequency when a guided projectile passes the side of the target by differentiating the output signal of the target, and outputs a pulse, and a digital signal output from the converter. A memory device for storing frequency data and outputting frequency data at predetermined time intervals centered on the pulse generation time of the differentiator according to the output pulse of the differentiator; A detection device comprising: a calculation section that performs calculation processing and calculates a guidance error.
