FMCWFrequency Modulated Continuous Wave Apparatus and Method for Calibrating a Receiver in a Monopulse Radar detecting a Target using Transmission/Reception Signal of an FMCW waveform
FMCWFrequency Modulated Continuous Wave Apparatus and Method for Calibrating a Receiver in a Monopulse Radar detecting a Target using Transmission/Reception Signal of an FMCW waveform
According to some embodiments, there is provided a method comprising: applying to a receiver an FMCW signal having a waveform of the same type as the transmit / receive signal; Obtaining first bit signals corresponding to the FMCW signals from the first channel, the second channel and the third channel of the receiver, respectively; Calculating a high angle correction term and an azimuth correction term based on the first bit signals; And correcting the elevation angle and azimuth angle of the target using the elevation angle correction term and the azimuth correction term. A method for correcting a receiver in a monopulse radar that detects a target using a transmission / reception signal of an FMCW waveform is disclosed.
