摘要： This radar device includes: a transmitter to transmit a transmitting signal whose frequency is periodically increased/decreased at a predetermined rate of change; a mixer to generate a beat signal by multiplying a received signal being transmitted by the transmitter and reflected back from an object to be detected and the transmitting signal; a frequency detector to detect a frequency of the beat signal; and a controller to control the rate of change of the frequency of the transmitting signal so that the frequency of the beat signal detected by the frequency detector becomes equal to or larger than a cut-off frequency of a flicker noise caused by the mixer.
摘要翻译：该雷达装置包括：发送器，用于以预定的变化率周期性地增加/减少频率的发送信号; 混频器，用于通过将由发送器发送并从被检测对象反射的接收信号与发送信号相乘来产生拍频信号; 频率检测器，用于检测拍频信号的频率; 以及控制器，用于控制发送信号的频率变化率，使得由频率检测器检测的拍频的频率变为等于或大于由混频器引起的闪烁噪声的截止频率。
