Description

The WDR77-VES is a digital radar that works

in the E-band. The sensor measures the

distance and the angle of objects in the front of

it and sends the measured data over CAN or

Ethernet to the host.

It is mounted on an airplane deicing truck and

used to measure the distance to the airplane

wing.

It features 2 transmit and 2 receiver channels

with a horizontal polarisation and also 2

transmit and 2 receiver channels in the vertical

polarisation. The transmitter antenna beam is

different for the 2 antennas and can be

switched over the CAN interface.

The sensor uses a range Doppler processing

to measure the distance of static and moving

objects. The 2 receiving channels are used to

measure the angle of the objects.
