Development and Manufacture

Model No. XRD

Keycom offers a wide range of systems for measuring and evaluating the performance of automotive radars and other mass-produced millimeter wave and microwave radars, including transmit power, frequency, antenna beam alignment, distance accuracy, angle accuracy, and reception performance.

We also develop and manufacture Radar Test Systems (RTS) to evaluate the distance accuracy and power output of radars, and Radar Alignment Systems (RAS) to adjust the mounting position of radars, upon your request.
