Abstract
The techniques of this disclosure relate to object range and velocity detections from varying radar pulse repetition times. A device includes a transmitter, a receiver, and a processor. The transmitter is configured to transmit a series of electromagnetic pulses within a frame having a varying pulse repetition time between electromagnetic pulses. A center frequency of the electromagnetic pulses varies by a frequency step. The receiver is configured to receive a series of corresponding reflected electromagnetic pulses reflected from an object. The processor is configured to determine range and velocity information of the object based on the received series of corresponding reflected electromagnetic pulses. By varying the pulse repetition times between consecutive pulses in a radar frame, the radar system may improve a range resolution, particularly in the case of frequency-modulated continuous-wave (FMCW) radar systems.
