Latest Patents

One of his latest patents is titled "Ambiguity mitigation for FMCW lidar system." This invention involves an FMCW Doppler lidar system designed for use in a host vehicle. The system includes a laser system, lenses, a homodyne receiver, and a signal processing unit (SPU). The laser beam is modulated to create a frequency waveform with three segments: Doppler, up-ramp, and down-ramp. The lenses transmit laser beams toward a target-of-interest and receive return beams reflected from that target. The homodyne receiver mixes the return beams with a local oscillator beam to generate a three-section return waveform. The SPU calculates the magnitude and frequency of the return waveform's sections, estimates their signs, and determines the range and velocity relative to the target, ultimately controlling the host vehicle.

Another significant patent is the "System and method for generating a frequency modulated linear laser waveform." This system utilizes a single frequency laser generator to produce a laser output signal. An electro-optical modulator then modulates the frequency of this signal to define a linear triangular waveform. The optical circulator passes this waveform to a band-pass optical filter, which filters out harmonic frequencies created during modulation, resulting in a pure filtered modulated waveform with a very narrow bandwidth. This modulated laser waveform is then transmitted to a target.
