Product Name:
The DUT is named ESR, which stands for Electronically Scanning Radar.
Users Manual / Operational Description:
The Device Under Test (DUT) is a 76.5 GHz vehicular radar. The device employs a
dynamic chirp modulated transmit array. Multiple transmit elements are employed for
long range operation and a subset of these same elements are used for medium range
operation. Multiple receive antennas are used to determine target angular resolution
through digital beam forming. When installed on a vehicle, the device will operate when
the vehicle is running, and the long range operation will be disabled when the vehicle is
at rest. The nominal operating voltage is 12.0 VDC.
The DUT is capable of two primary modes of operation, long range and medium range.
Long range transmission employs a greater number of array elements, resulting in a
higher total EIRP. Long range modulation employs a chirp rate with a frequency span of
100 MHz. Mid-range modulation employs a chirp traversing 200 MHz.
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with minimum distance of
20 cm between the radiator and your body. This transmitter must not be co-located or
operating in conjunction with any other antenna or transmitter.
