Radar apparatus for contemporaneous sending of signals with constant frequency offset, has control unit that controls oscillator such that signal fragments of primary signal are followed each other directly

摘要

#CMT# #/CMT# The apparatus has an oscillator (2) that generates a primary signal having a sequence of signal fragments with different frequencies. A frequency increment of frequencies of signal fragments increases or decreases during a clock of signal fragment. An oscillator (6) generates a secondary signal in synchronous with the primary signal. The oscillator (2) is controlled by a control unit (1) such that the signal fragments of the primary signal are followed each other directly and the secondary signal is sent over a same transmitter antenna (3) as that of primary signal. #CMT# : #/CMT# An independent claim is included for method for operating radar apparatus. #CMT#USE : #/CMT# Radar apparatus for contemporaneous sending of signals with constant frequency offset. #CMT#ADVANTAGE : #/CMT# Since the distortions in the radar apparatus can be prevented effectively, the reliable and accurate measurements in the radar apparatus can be ensured. The large frequency jumps due to the change in the signal fragments can be prevented effectively so that the transient response of the radar apparatus can be improved efficiently and the settling time of the radar apparatus can be shortened effectively. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of the radar apparatus. 1 : Control unit 2,6 : Oscillators 3 : Transmitter antenna 4 : Receiving antennas 5 : Mixer.
