Signal software simplifies multi-emitter scenario generation for aerospace/defence

April 02, 2015 // By Graham Prophet
Keysight Technologies’ N7660B Signal Studio for multi-emitter scenario generation (MESG) I a software package that provides aerospace/defence engineers with performance-optimised, Keysight-validated multi-emitter signals that they can download to one or more Keysight N5193A UXG agile signal generators for effective testing of electronic countermeasures (ECM) systems.

Creating realistic multi-emitter scenarios is a complex challenge that involves correctly interleaving multiple pulse trains as well as identifying, counting and prioritising pulse collisions. Managing all these parameters manually can be a daunting task. With the MESG capability, Signal Studio simplifies threat interleaving for ECM system test applications such as sorting and identification, subsystem interface management and threat correlation.

A graphical user interface allows test engineers to configure radar parameters such as frequency, amplitude and pulse width, and then interleave multiple radar emitters. This includes the ability to combine radars into scenarios using dropped-pulse reports to optimise pulse density. Engineers can reduce pulse collisions by changing emitter start times, priorities and pulse-repetition intervals, by toggling emitters on and off, and by adding more UXG signal generators to the simulation.

Engineers can download the multi-emitter scenarios, created in Signal Studio, directly to one or more UXGs as pulse descriptor word (PDW) lists. The UXG provides phase-coherent frequency and amplitude transitions as fast as 180 nsec, timing resolution of 2 nsec, and spurious-free dynamic range of -70 dBc.
