Implementation of a sidelobe blanking system on the AN/SPS-12 radar.
implementationof00aran.pdf (10.16Mb)Abstract
A sidelobe blanking system can be looked upon as a
method for maximizing main-lobe-detection and minimizing
sidelobe detection. The system is intended to provide only
main-beam signals and thereby producing unambiguous bearing
information.
The sidelobe blanking system turns the video off when
the signal in an auxiliary antenna is stronger than the
signal in the main antenna. Sidelobe blanking is best for
pulse interference, and is not suitable for sidelobe noise
jamming.
In order to carry out experiments with sidelobe blanking
a system was implemented on the AN/DPS-1 and AN/SPS-12 radar
sets.
The theory of sidelobe blanking and the design and
implementation of the working circuits used is presented,
together with pictures of the system and examples of the
displayed signals and results.
