Claims

[Scope of utility model registration request]

An antenna used for both transmission and reception, which emits transmitted radio waves to the outside and receives reflected waves, interference waves, and abnormal waves from the target in a radar device that has the function of searching, detecting, and tracking a target, and also receives echoes from the target. generates high-frequency pulse power and amplifies the received radio waves,
a transmitting/receiving module having a pulsed power supply section necessary for generating high-frequency pulsed power; a transmitting/receiving switching section that switches between a received radio wave inputted from the antenna and a transmitted radio wave outputted from the transmitting/receiving module; An exciter that generates high-frequency pulses for generation, a receiver that processes the waveform of received radio waves, a frequency conversion mixer that converts the received radio waves to an intermediate frequency, and a local signal that converts the received radio waves to an intermediate frequency. a local signal generation section that generates a signal, a receiver section that amplifies the output of the frequency conversion mixer and then outputs it as a video signal, and a signal that receives the output of the receiver section and processes the signal for search, detection, and tracking. A radar device comprising: a processing section; and an interference wave display section that receives the output of the receiver section and displays an interference wave if it is present in the signal.
