Electromagnetic simulation of mono-pulse DF antenna configurations

The scheme of mono-pulse direction finding is well established. This paper uses a method of electromagnetic simulation to evaluate the direction finding performance of a number of common mono-pulse schemes. The mono-pulse variants include amplitude comparison of mechanically squinted beams, electronic squint and a linear interferometer. The advantage of simulation is that performance and other features of each scheme can be evaluated prior to implementation. The electromagnetic simulation is based on readily available Method of Moment (MOM) code with additional post processing. This work is applicable to situations that require emitter direction information such as cognitive radio systems, smart communication networks and electronic warfare.
