Multi-echo function (Special for Outdoor)

Multi-echo function (Special for Outdoor)
Multi-echo(LX mode):
You can receive multiple echoes such as rain or fog in one direction and select the distance data from each.

Filter function(LA mode):
If there is no continuous object in the same place (STEP) with the rain filter,it will be removed.

Interference prevention

Interference prevention
Synchronous operation or interference mitigation mode are effective
to prevent multi interference between sensors.

Mode switching

Mode switching
Area setting type(LA mode) and data output type(LX mode) can be switched.
Environmental recognizion and obstacle detection are possible only with this one.
