Claims

[Scope of utility model registration request]

In a radar device that has the function of searching, detecting, and tracking a target and also receives echoes from the target, it includes an antenna that emits transmitted and received radio waves to the outside and receives reflected waves from the target, and a transmitting and receiving module that generates high-frequency pulsed power. , a liquid cooling section of the transmitting/receiving module, a transmitting/receiving switching section for switching the transmitting radio waves output from the antenna, an exciter for generating high frequency pulses for generating the transmitting radio waves, and a receiver for processing the waveform of the received radio waves. , a frequency conversion mixer that converts the frequency of the received radio wave to an intermediate frequency, and a local signal generator that generates a local signal for converting the received radio wave to an intermediate frequency;
A radar device comprising a receiver section that amplifies the output of the frequency conversion mixer and then outputs it as a video signal, and a signal processing section that receives the output of the receiver section and performs signal processing for search, detection, and tracking, an outside temperature detection section that detects the outside temperature and generates an abnormally low temperature state detection signal when the outside temperature falls below a preset temperature; and a cooling section that operates based on the abnormally low temperature detection signal and cools the transmitting and receiving module. A radar device characterized by being provided with.
