In a frequency-modulated continuous-wave radar processing system and method, a linear frequency ramp signal is defined. The linear ramp signal is divided into time sections. The sections of the linear ramp signal are rearranged in time such that the sections define a transmit control signal different than the linear ramp signal. A radar transmission signal is generated having a frequency varying with time according to the transmit control signal, and the radar transmission signal is transmitted into the region of interest. An intermediate frequency signal is generated using the radar transmission signal and radar receive signals received from the region of interest, a frequency of the IF signal being a difference between the frequency of the radar transmission signal and a frequency of the radar receive signals. Radar processing is performed on the low-pass-filtered IF signal. |
