摘要： The subject invention pertains to a frequency modulation continuous wave (FMCW) radar system. Embodiments relate to methods of improving the performance of such a FMCW system and improving the value of the information provided by such a FMCW system. In an embodiment of the subject invention, the IF level can be monitored while sweeping the frequency of the system through at least a portion of the frequency range of the system. In a specific embodiment, the system is then set to the frequency that produces the minimum IF level, which is the frequency that produces the minimum AM signal level. Embodiments of the invention pertain to techniques for expediting the adaptation of the comb filter to the signal when the system is turned on. In an embodiment, in order to reduce the number of detection calculations a processor performs every frame, a method of quickly determining the largest peaks in the RDM is implemented. Embodiments of the subject invention relate to a method for processing a radar signal that classifies two or more targets. A specific embodiment of a method for processing the radar signal classifies a human target or other target(s) using amplitude values in time-consecutive range-Doppler maps. Embodiments of the invention pertain to a method for processing a radar signal for improving the performance of FMCW detection, tracking, and classification algorithms. Embodiments improve such performance by increasing the SNR and velocity measurement resolution of slow moving targets while minimizing DSP computational and memory requirements in two-dimensional FFT range-velocity processing.
