Radar microsensor for detection, tracking, and classification

摘要

Embodiments pertain to methods of improving the performance of a frequency modulation continuous wave (FMCW) radar system and improving the value of the information provided the FMCW system. In an embodiment, the IF level is monitored while sweeping the frequency of the system through at least a portion of the frequency range of the system and the frequency is set to produce the minimum IF level. Embodiments expedite the adaptation of the comb filter to the signal when the system is turned on. In an embodiment, a method of quickly determining the largest peaks in the RDM is implemented. Embodiments relate to a method for processing a radar signal that classifies two or more targets. An embodiment classifies a human target or other target(s) using amplitude values in time-consecutive range-Doppler maps. An embodiment processes a radar signal for improving the performance of FMCW detection, tracking, and classification algorithms.
