DBF Imaging Radar
Prole
The all-new DBF imaging radar works during both day and night, without being affected by light or dust.
In an optimal operating environment, the radar module can predict the distance between the aircraft and
the vegetation or other surfaces in forward, rear, and downward directions to fly at a constant distance to
ensure even spraying and terrain following capability. The DBF imaging radar can also detect obstacles
30 m away from the aircraft. The radar module adopts digital beam forming technology, which supports
3D point cloud imaging that effectively senses the environment and helps to circumvent obstacles in
both Route and A-B Route operation modes. In addition, radar module limits the descent speed of the
aircraft according to the distance between the aircraft and ground, to provide a smooth landing.
The altitude stabilization and obstacle avoidance functions of the radar module are enabled by default,
and can be disabled in the app. When enabled, the aircraft flies above the vegetation at a constant
spraying distance in Route, A-B Route, and Manual Plus operation modes. In Manual operation mode,
the radar module can also measure the spraying distance above the vegetation or other surfaces, but
the aircraft is not be able to fly at a constant spraying distance. The obstacle avoidance function can be
used in any mode. Auto Bypass is disabled by default. Users can enable it in the app.
Detection Range
The detection range of the radar module is depicted as follows: The horizontal detection range is
±50° and the vertical detection range is 0° to 10°, as shown below. Note that the aircraft cannot sense
obstacles that are not within the detection range. Fly with caution.

Obstacle Avoidance Function Usage
The effective horizontal detection range varies depending on the size and material of the
obstacle. For example, when sensing objects that have a radar cross section (RCS) of -5 dBsm,
the effective horizontal detection range is approximately ±38°. When sensing objects such
as power lines that have a RCS of -10 dBsm, the range is approximately ±28°. When sensing
objects such as dry trees branches that have a RCS of -15 dBsm, the range is approximately
±14°. Obstacle sensing may malfunction or be unavailable in areas outside of the effective
detection range.
