Claims

[Scope of utility model registration request]

High-frequency power is radiated from the antenna to the outside as a transmitted radio wave to not only track or search for the target, but also when the target generates interference waves, it stops transmitting itself to the source of the interference waves and transmits the interference waves. A radar device having a function of detecting interference waves that can receive signals and perform angular tracking includes a high-frequency power generation source that generates high-frequency power, and a radio-frequency power source that radiates the high-frequency power to the outside as a transmission radio wave, and also has a radio-frequency power generation source that generates high-frequency power as a transmission radio wave. A transmitting/receiving antenna that receives reflected waves and interference waves, a transmitting/receiving switch that performs switching between transmitting radio waves from the high frequency power generation source and receiving radio waves from the antenna, and transmitting and receiving radio waves. A local oscillator for converting to an intermediate frequency, a receiving mixer preamplifier, a receiving section that amplifies the output of the mixer preamplifier and outputs it as a video signal, and a receiving section that receives the video input from the receiving section and calculates the target distance. A signal processing unit that processes tracking and angle tracking and issues commands for interference waves from the target, a loop coupler that extracts a portion of the power from the high frequency power generation source, and a A mixer preamplifier amplifier, a disk discriminator, and a memory circuit that normally outputs the output of the disk discriminator as the drive voltage of the local oscillator as it is, but when a command from the signal processing section comes, it holds the drive voltage at that time. Equipped with radar equipment.
