Abstract: Embodiments of the subject invention relate to a method and apparatus for signal processing that reduces the average power used in a small size, frequency modulated continuous-wave (FMCW) radar. Such a small size, frequency modulated continuous-wave (FMCW) radar is referred to herein as a micro radar. Specific embodiments of the invention can be used to detect and/or track personnel, vehicle, and/or other targets.

Abstract: 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.

Abstract: 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.
