Distance Test to Airborne Planes
Technical Overview
Introduction
Keysight Technologies, Inc. pulse generators are used for testing radar communication
systems in the military industry, and as demonstrated in this technical overview, the
aviation industry.
A trigger pulse train of double pulses is sent from the control tower's radar system to an
airborne plane. The plane responds with a standard signature signal which is sent back to
the control tower. This occurs up to 450 times per second. The control tower receives the
signal, recognizes its signature, and then analyzes the delay to determine the distance
between the tower and the airborne plane.
To test a radar system on a regular basis, an 81150A is used to simulate the signature signal.
Varying the delay from the external trigger to the start of the output signal, various distances
from the control tower can be simulated. This delay can be up to 2 ms. Therefore, it has to
be created by leading zeroes added to the signature signal.
Due to the legal safety requirements, it is critical to have very accurate edge placement
of the pulses. The 81150A has a frequency accuracy of
