装置。 In a radar device that has the function of searching, detecting, and tracking a target, and also receives echoes from the target, an antenna for both transmitting and receiving that emits transmitted radio waves to the outside and receives reflected waves and abnormal waves from the target; a transmitting/receiving module that generates high frequency pulse power, amplifies received radio waves, and has a pulse power supply section necessary for generating the high frequency pulse power; a received radio wave input from the antenna; and a transmitting/receiving module output from the transmitting/receiving module. a transmission/reception switching unit that switches transmission radio waves, an exciter that generates high-frequency pulses for generating transmission radio waves, a receiver that processes the waveform of the reception radio waves, and a frequency conversion mixer that converts the frequency of the reception radio waves to an intermediate frequency; a local signal generation section that generates a local signal for converting the received radio wave to an intermediate frequency; a receiver section that amplifies the output of the frequency conversion mixer and outputs it as a video signal; and a receiver section that receives the output of the receiver section. If there is an abnormal reflected wave in the received radio waves output from the signal processing unit that performs signal processing for search, detection, and tracking, and the above-mentioned transmission/reception switching unit, this abnormality is detected and switched so that it is not output to the above-mentioned transmission/reception module. A radar device comprising a reflected wave processing section.
