The near field suppression zone can be configured with the user parameter:
Near-field suppression zone, min=0
The current near field range can be obtained by the parameter
Const: Near field suppression range [0.1 mm]

Example:
Zone 3 has been set as near field suppression range. Any echo from a target in the
range will be ignored:
Near_field_range = zone0 + zone1 + zone2 + zone3
