Claims

[Scope of utility model registration request]

A radar device that has the function of searching, detecting, and tracking a target, and also receives echoes from the target, has an antenna that radiates transmitted radio waves to the outside and receives reflected waves and abnormal waves from the target, and a high-frequency pulse power. a transmitting/receiving module having a pulse power supply section necessary for generating, amplifying received radio waves, and generating high-frequency pulse power; an antenna abnormal state detecting section for detecting an abnormal state in the antenna when it occurs; a transmission/reception switching unit that switches between a received radio wave inputted from the antenna and a transmitted radio wave outputted from the transmission/reception module; an exciter that generates a high-frequency pulse for generating the transmitted radio wave;
a receiver that processes the waveform of the received radio wave; a frequency conversion mixer that converts the frequency of the received radio wave to an intermediate frequency; a local signal generator that generates a local signal for converting the received radio wave to the intermediate frequency; After amplifying the conversion mixer output,
A radar device comprising: a receiver section that outputs a video signal; and a signal processing section that receives the output of the receiver section and performs signal processing for search, detection, and tracking.
