Claims (1)

[Scope of utility model registration request] An antenna used for both transmitting and receiving purposes, 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. and,
a transmitter section that generates high-frequency pulsed power; a detection section that detects the transmission state and reception condition in the transmission and reception module; and a detection section that detects malfunction conditions; and a switching circuit that switches the transmission direction of the transmission and reception signals in the antenna and the transmission and reception module. , a malfunction display section that displays a malfunction in the detection section; a transmission/reception switching section that switches to receive radio waves input from the antenna; a frequency mixer that performs conversion, a signal generation section that generates a local signal for converting the received radio wave to an intermediate frequency, and a receiver section that amplifies the frequency mixer output and then outputs it as a video signal;
A signal processing section that receives the output of the receiver section and performs distance tracking and angle tracking processing, and the output of the receiver section is input, and if there is an interference wave in the signal,
A radar device comprising an interference wave display unit that displays this.
