    摘要: A ghost removal method includes steps of detecting, estimating and excluding. In the detecting, a position and a relative speed of a target moving object, and a position of a surrounding stationary object are detected with radio waves. In the estimating, a position and a relative speed of a ghost by the target moving object are estimated based on the detected position and relative speed of the target moving object and the position of the surrounding stationary object. In the excluding, a detected point where the estimated position and the relative speed of the ghost are detected is excluded from a candidate detection point of a moving object which is detected with radio waves.

    摘要: The embodiments described herein provide a radar device and method that can provide improved sensitivity. In general, the embodiments described herein provide a saturation detector and reset mechanism coupled to a radar receiver. The saturation detector is configured to detect saturation events in the radar receiver, and the reset mechanism is configured to reset at least one filter unit in the radar receiver in response to detected saturation events. As such, the embodiments can facilitate improved radar sensitivity by reducing the effects of saturation events in the radar receiver.

    摘要: Embodiments are provided for a radar device and a method of operating a radar device, the radar device having a transmitter and a receiver, the method including: generating a chirp signal based on a local oscillator (LO) signal, wherein the LO signal is a frequency-modulated continuous-wave (FMCW) signal; secondary modulating the chirp signal to produce an output signal; transmitting the output signal on a transmitting antenna of the radar device; receiving an echo signal on a receiving antenna of the radar device; downmixing an amplified version of the echo signal with the LO signal to produce a low frequency signal; and outputting an error detection signal based on spectral components of the low frequency signal, wherein the spectral components correspond to the secondary modulating.
