From circuit topology to behavioral model of power amplifier dedicated to
radar applications
Background
In the recent years, active electronically scanned array (AESA) radars are
gaining more importance in military radar systems. However, the AESA
radars are two times more expensive than the older generation radars. To
make products that are cost effective, accurate simulations of the radar are
very important. So far the old simulations cannot accurately predict the
outcomes because they cannot take into account of certain specifications for
each radar system. This paper presents the “Grey Box Model” which is an
improved simulation system that can accurately predict the behavioral
models of modern radars.
Method
The researchers build a system that includes both passive and active
elements as parameters into the model, which means there are linear and
non-linear sub-models. These models are then complied together into a
larger behavioral model.
Results
The system was used in Agilent Advanced Design System, and the data files
coming out successfully describe the relations between the input
parameters and the model behavior.
Conclusion
The researchers have presented a new way of conducting accurate
simulations. And this method should be incorporated into the French
Defense and Security Agency (DGA) AESA radar simulation tool.
