ダ装置。 In a radar device that not only has the function of searching or tracking a target, but also has the function of detecting interference waves from the target, an antenna used for both transmission and reception, which radiates the transmitted radio waves to the outside and receives reflected waves and interference waves from the target. a transmitter section that creates a high-frequency power pulse; a transmission/reception switching section that performs switching between transmitting radio waves from the transmitter section and receiving radio waves from the antenna; and input from the transmission/reception switching section. A mixer that converts the frequency of received radio waves to an intermediate frequency, a local signal generator that creates a local signal for converting the received radio waves to an intermediate frequency, and a receiver section that amplifies the mixer output and outputs it as a video signal. , a signal processing section that receives the output of the receiver section and processes distance tracking and angle tracking, and creates various gates and triggers, and a gate for detecting interference waves created by the trigger input from the signal processing section. arbitrarily setting or moving the positions of an interference wave detection circuit that detects interference waves present in the input signal from the receiver section using the interference wave detection circuit; and an interference wave detection gate created by the interference wave detection circuit; What is claimed is: 1. A radar device comprising: a gate position setting circuit capable of detecting interference; and an interference wave display section that receives an output from the interference wave detection circuit and reports the presence of interference waves.
