成したことを特徴とするレーダ装置。 A radar device having a function of not only searching or tracking a target but also detecting spinning waves from the target includes a transmitter unit that generates a high-frequency power pulse, and radiates the high-frequency power pulse to the outside as a transmission radio wave, Also, a transmitting/receiving antenna that receives reflected waves and jamming waves from the target, and a transmitting/receiving switch that performs switching between transmitting radio waves from the transmitter section and receiving radio waves from the antenna;
After frequency-converting the received radio wave input from the above-mentioned transmitting/receiving switch to an intermediate frequency band and amplifying the signal,
a receiver unit that outputs a video signal; a video distributor that distributes the output of the receiver unit; and a video distributor that receives the output from one of the video distributors and issues commands for processing distance tracking, angle tracking, and spinning waves. an interference wave detection circuit that inputs the other output of the video distributor and detects whether it is a pulse interference wave or a continuous wave interference wave; and an interference wave detection circuit that receives the output of the interference wave detection circuit. What is claimed is: 1. A radar device comprising: an interference wave display unit that displays either pulse interference waves or continuous wave interference waves;
