1.5 SMART7 Emulated Radar

1.5.1 Emulated Radar (ER)

A typical radar sensor emits radio beams that bounce off the ground and computes ground speed
based on the speed at which objects are passing in front of the sensor. The output of the sensor
is a digital pulse, the frequency of which is proportional to the vehicle's ground speed. This is
often used in agricultural applications such as planting and spraying. The SMART7 eliminates the
need for separate ground-sensing radar equipment by converting the GPS-derived velocity to
proportional frequency output. The following emulated radar signal parameters can be con-
figured by the customer:
Frequency Step: Specifies how the frequency output relates to the vehicle speed.
l
Signal Update Rate: Specifies how often the frequency output is updated to match the
l
vehicle speed.
Response Mode: Specifies how quickly changes in velocity are reflected in the frequency out-
l
put. Setting a slower response mode reduces spikes (noise) in the velocity but increases
latency. Setting a higher response mode reduces latency, but may result in noisier frequency
output.
Refer to RADARCONFIG command for detailed information.
After it is configured using the RADARCONFIG command, Emulated Radar (ER) pulses are out-
put through the SMART7 interface cable and the RADARSTATUS log.
