Practical Consideration Factors to Design Array Configuration of Direction Finding System for Airborne Signal Intelligence

Abstract EN

Airborne signal intelligence (SIGINT) systems must be capable of locating radio signal sources.

Direction finding (DF) to support this capability is an important factor.

There are some practical considerations to be taken when designing the array configuration of a DF system for airborne SIGINT systems.

This paper summarizes the practical factors when designing the array configuration of the DF system for airborne SIGINT.

In particular, it focuses on four areas: antenna consideration factors when installing the DF system for airborne SIGINT from a practical point of view, array configuration methods for airborne communications intelligence and electronic intelligence, and a numerical analysis to select the optimum antenna position for airborne SIGINT.
