  • Publication number: 20200136564
    Abstract: In a case where the power of a signal to be amplified is greater than or equal to a threshold value, a signal distributor (2) outputs one of signals to a carrier amplifier (6), outputs another signal, a phase of which is 90 degrees behind that of the one of the signals, to a peak amplifier (8), and adjusts a phase shift amount of a signal shifted by a phase shifter (7) depending on the frequency of the signal to be amplified. In a case where the power of the signal to be amplified is less than the threshold value, the signal distributor (2) outputs the one of the signals to the carrier amplifier (6) without outputting the other signal to the peak amplifier (8).

  • Patent number: 10353050
    Abstract: A radar apparatus generates a spectrum distribution where frequencies in a beat signal are associated with intensities of respective frequency components. Based on a plurality of spectrum distributions generated over a predetermined number of measurement cycles prescribed in advance, the radar apparatus generates a reflection intensity distribution where frequencies are associated with road surface reflection intensities of the radar wave from a road surface at each frequency. In the reflection intensity distribution, the radar apparatus detects an intensity peak indicating a frequency that maximizes the road surface reflection intensity. Based on the detected intensity peak, the radar apparatus determines at least whether or not the radar apparatus is in an axis deviation state that is taken as a state where a reference axis of the radar apparatus has an inclination of not less than a prescribed angle in a vehicle height direction relative to a horizontal axis prescribed to a vehicle.
