1 Sensor RF Performance Validation

Described below are the basic production checks done on a radar module at high-level:

  • Basic power-on checks
    • Current drawn at power up
    • Digital Interface checks
  • Factory Calibrations
    • Antenna beam tilt measurement
    • Range bias and receiver channel gain/offset compensation
  • Parametric checks – Corner Reflector setup
    • Transmitter-receiver loopback SNR

Sensor performance validation can cover the entire range of sensor hardware and software subsystems. This document is not intended to serve as a reference for hardware bring up or validation. Instead, this section describes a high-level overview of the production line testing done on fully validated and characterized hardware to screen for issues on a production ready sensor. These issues generally arise from handling defects, environmental factors, assembly defects, and manufacturing defects.
