  • Radar system and method for determining range, relative velocity and bearing of an object using continuous-wave and chirp signals
    Patent number: 9383442
    Abstract: Determining distance and relative speed includes a transmitter transmitting electromagnetic signals defined by a plurality of sections, a first section comprising a continuous-wave (CW) signal, a second section comprising a chirp electromagnetic signal, the chirp electromagnetic signal comprising a plurality of subsections. A detector detects reflected signals being the transmitted electromagnetic signals reflected from an object, and comprising a reflected CW signal and a reflected chirp signal. The detector detects the reflected signals by: (i) generating a plurality of samples of the reflected CW signal, and (ii) generating a plurality of samples of the reflected chirp signal. A processor determines a first set of phase differences among the plurality of samples of the reflected CW signal and a second set of phase differences among the plurality of samples of the reflected chirp signal, and processes the first and second sets of phase differences to determine the distance, relative speed and bearing.
