Radar Digital Signal Processing Engineer

Company: Perceptive
Location: San Francisco
Posted on: January 16, 2022

Job Description:

Perceptive is reinventing the way driverless vehicles sense and perceive the world. We have uprooted the conventional sensing and perception system of autonomous vehicles (lidars, radars, cameras, etc.), and replaced it with a fundamentally new solution, based on entirely new hardware and software: integrated, centralized, software defined. Perceptive changes everything. Not only can autonomous vehicles finally sense and make sense of the world as a human would, but they can also be built at scale and be broadly deployed.
As radar DSP engineer, youll be responsible for designing, simulating, and validating radar signal processing algorithms for a variety of hardware architectures. Youll work closely with our teams of FPGA, GPU, and RF designers to implement the DSP into our compute platform, as part of a multimodal sensing system, including laser and optical modalities. You will explore new DSP algorithms for the future generations of our system and your ideas will directly influence our next gen architecture.
Requirements

  • Deep hands-on experience with digital and statistical signal processing fundamentals such as sampling and reconstruction, time and frequency-domain analysis of LTI systems, FIR/IIR filter design methods, random processes, Markov chains, wavelets, etc.
  • Deep working knowledge of signal estimation and inversion techniques such as least-squares and least-norm methods, convex optimization, Kalman filters, Wiener filters, MAP and ML estimation
  • Intimate knowledge of state of the art mm-wave MIMO imaging radar hardware architectures such FMCW and PMCW. Familiar with the tradeoffs between radar hardware parameters such as antenna pattern and number of elements and ADC sampling rates and system level performance metrics such as radar range, azimuth and elevation resolution, unambiguous velocity range, etc.
  • Hands-on experience with classical end-to-end imaging radar DSP with deep understanding of the tradeoffs between DSP parameters and system-level performance metrics
  • Familiar with advanced imaging radar DSP techniques such as super-resolution methods, MUSIC, ESPRIT, 2D and 3D tracking, multi-dimensional CFAR, etc.
  • Hands-on experience with bringup, test and characterization of radar hardware and statistical analysis of real test data
  • Hands-on with common scripting languages such as Python, Matlab or R
    • Creative go-getter and great team player with good communication skills. Comfortable with working in very fast paced multi-disciplinary environments.
      Pluses
      • Working knowledge of digital communication principles such as modulation, demodulation and detection schemes, noise, SNR and BER analysis, equalization, error correction coding, etc.
      • Experience with novel AI/ML techniques for radar detection and tracking
      • Knowledge of the fundamentals of electromagnetic fields and waves such as
      • free-space wave propagation, scattering, etc.
      • Familiarity with radar antenna design principles such as antenna radiation pattern
      • and gain calculation, etc.
      • Experience with electrical lab equipment such as oscilloscopes, power supplies,
      • spectrum analyzers, active loads, etc.
      • Experience with test and characterization of electrical modules such as AC-DC and
      • DC-DC converters, high-speed mixed-signal modules, sensors, etc.
      • Familiarity with sensing and perception pipelines for level 4 and 5 autonomy
        Background
        • Masters or Ph.D. degree in Electrical engineering, Physics or other related fields
        • 5+ years of radar DSP design work
        • Track record of product delivery in automotive or consumer electronics markets
