Claims

[Scope of utility model registration request]

In a radar device that has the function of searching for, detecting, and tracking a target, it emits transmitted radio waves to the outside,
A transmitting and receiving antenna that receives reflected waves from the target, a circulator that isolates transmission and reception, a transmitter section that outputs high-frequency power pulses, a stabilizing oscillator section with a fixed frequency, and a After converting the input into an intermediate frequency signal, a receiver section receives a signal from a defruter circuit (described later), removes the asynchronous signal at an intermediate frequency stage, and then outputs it as a video signal, and a a local signal generation unit that receives the signal and generates a local signal to be used in the receiver unit;
Detection of search video based on the output of the receiver section,
By performing the signal processing section that performs angle tracking and distance tracking, and the inter-human correlation processing, which was conventionally performed in the signal processing section, within the receiver, the receiver is prevented from being saturated by asynchronous signals, etc. A radar device comprising a defruer circuit that prevents.
