Abstract: The present invention relates to a digital frequency modulated continuous wave (FMCW) radar altimeter and an altitude search method thereof. The FMCW includes: a transmitter that includes a direct digital synthesizer to create the FMCW using the digital synthesizer, and transmits the created FMCW in the form of a transmission signal onto the ground surface; a receiver that receives a reception signal reflected from the ground surface, mixes the reception signal and the transmission signal with each other to create a bit frequency signal having a differential frequency between the two signals, and converts the bit frequency signal into a digital signal; and a signal processing unit that detects the distance from the ground surface using the converted digital signal and outputs the detected distance. The signal processing unit divides a whole section from the minimum distance to the maximum distance into m sections and sets mutually different reference distances to the m sections. The signal processing unit controls the direct digital synthesizer to create an FMCW having a modulation bandwidth corresponding to the n^th reference distance during the unit time based on the n^th reference distance set to the n^th section among the m sections. The signal processing unit detects the distance from the ground surface using the modulation bandwidth corresponding to the converted digital signal and the n^th distance. The n is in the range of 1 to m to detect the distance from the ground surface.

Abstract: PURPOSE: An FMCW radio altimeter having a wide altitude range and small measurement error and an altitude meauring method thereof are provided to determine an altitude in a wide altitude range with a small measurement error at a time, and counteract signal jamming by enabling frequency hopping. CONSTITUTION: A transceiver (200) comprises an offset frequency generator (210), an RF signal generator (240), an I/Q modulator (220), a transmission/reception separator (230), and a frequency mixer (250). The offset frequency generator deviates a frequency as much as a variable offset frequency that is set according to a control signal from an control operator (400). The RF signal generator generates an FMCW signal. The I/Q modulator performs frequency up-conversion by mixing an output signal from the offset frequency generator with an output signal from the RF signal generator. The transmission/reception separator separates signals that are transmitted from or received in an antenna unit (300). The frequency mixer generates a beat frequency by mixing an output signal from the RF signal generator with a signal received through an antenna.
