ていることを特徴とするレーダ装置。 A radar device that has the function of searching, detecting, and tracking a target, and also receives echoes from the target, emits transmitted radio waves to the outside and collects reflected waves from the target.
A receiving antenna that receives interference waves and abnormal waves, a transmitter section that generates high-frequency pulse power, a detection section that identifies and detects abnormal waves in radio waves received from the antenna, and transmits and receives the abnormal waves. A switching circuit that switches so as not to send out to the switching circuit, an abnormal wave display section that displays that the abnormal wave has been detected, transmission of radio waves from the transmitter section, and reception that is input from the antenna via the switching circuit. A transmission/reception switching unit that performs switching to receive radio waves, a frequency mixer that converts the frequency of the received radio waves input from the transmission/reception switching unit to an intermediate frequency, and a local signal for converting the received radio waves to the intermediate frequency. is a local signal generation section that generates a local signal, a receiver section that amplifies the frequency mixer output and then outputs it as a video signal, and a signal processing section that receives the output of the receiver section and processes distance tracking and angle tracking. and a disturbance display section which receives the output of the receiver section and detects and displays disturbances present in the signal.
