Claims

[Scope of utility model registration request]

An antenna that receives the reflected wave from the target, a sweep circuit, and a mixer that mixes the reflected wave from the target received by the antenna with the output of the voltage controlled oscillator and extracts the intermediate frequency of the difference. an intermediate frequency amplifier that amplifies the intermediate frequency and suppresses noise at the same time; a frequency discriminator that outputs a voltage proportional to the input frequency; a DC amplifier that amplifies the output of the sweep circuit and the frequency discriminator; An automatic frequency control circuit consisting of a switch that connects or disconnects the frequency discriminator and DC amplifier, and a voltage controlled oscillator that receives the output voltage of the frequency discriminator or sweep circuit as input and generates a frequency proportional to the voltage. a detection circuit for detecting the presence or absence of Doppler information from the target; and means for storing target speed information sent from the radar before launching the guided flying object and controlling the search range of the sweep circuit based on its output. A receiver for a guided flying body, characterized by comprising:
