Abstract

Radar signal emulation systems have been used by the Brazilian Air Force in order to test on-board electronic warfare receivers. Among the several radar parameters simulated by these systems, the type of scan and radiation diagram of the radar antenna is an important feature to be considered, usually implemented through variable attenuators installed in the radiofrequency (RF) output. This work presents a new technique for simulating the characteristics of the radar antenna, implemented by varying the power gain of an analog link to optical fiber, controlled through a Virtual Instrument (VI) constructed in LabVIEW. The optical fiber link is used with the objective of transmitting the emulated RF signals to a remote antenna. The validation of this technique is carried out through theoretical formulation and an experimental demonstration.
