Create complex, high pulse density EW scenarios and simulate AoA and kinematics (moving platforms) simultaneously based on coherent, multiple Keysight N5191A/93A UXG agile signal generators. The Multi-Emitter Scenario Generator, Reference Solution is a combination of UXGs, calibration hardware and software, along with Signal Studio application software that has been configured to simulate an electronic battlefield with thousands of emitters.

Fast frequency hopping with phase continuity and repeatability enables Keysight’s UXG agile signal generator to simulate multiple pulse-Doppler radars (multiple emitters) at different frequencies while maintaining its original phase. With multiple UXGs, you can simulate EW scenarios with thousands of radar threat-emitters and millions of pulses per second (the pulse density scales with the number of UXGs). In addition to simulating high pulse density, it’s extremely important to create AoA on all RF pulses for two reasons: 1) AoA allows the EW receiver to localize threats for neutralization and 2) AoA is a primary threat sorting parameter and thus allows the EW receiver to identify groups of pulses as belonging to individual threats.

Creating AoA means: staggering identical pulses played out of different ports (different UXGs), in time, phase, amplitude, or all three. In order to properly stagger these pulses, the UXGs must be phase, time, frequency and amplitude aligned (calibrated) with each other. The Multi-Emitter Scenario Generator, Reference Solution includes tailored calibration routines that work with a number of different measurement receivers — the PNA and PNA-X vector network analyzers, Infiniium oscilloscopes, and U2000 power sensors so that you can choose the right tool for the job. It is this process of calibration that ultimately controls how accurately you can simulate AoA for EW receiver test.

Beyond realistic AoA simulations, this reference solution provides other advantages including size, cost, and procurement time. Traditional EW systems have been developed using large, expensive, proprietary test systems that have long lead times and provide limited support for ongoing end user customization. This reference solution hardware, small enough to fit on an engineer’s desk, is configured with COTS test equipment at a fraction of the cost of typical EW test systems. Because it incorporates COTS hardware and software, it can be delivered in months instead of years and is inherently more reliable than large, complex, proprietary EW systems.
