<p>Disclosed is a method for controlling the transmission time of a radio frequency (RF) signal in an FMCW device. The method includes: a transmitting/receiving step of transmitting an RF signal according to a transmission command by using a transmitting antenna and receiving the RF signal reflected on the ground in response thereto by using a receiving antenna; a signal processing step of digital-signal-processing the received RF signal; and a control step of measuring an altitude based on digital-signal-processed data and generating the transmission command to control the transmission time of the RF signal according to a change rate of the measured altitude, thereby minimizing influence on an external interference signal.</p> |
