Get Closer to Reality

To accurately simulate radar threats and targets, an agile signal generator that can switch frequency and settle amplitude in the hundreds of nanoseconds at different frequencies is necessary. When looking for a solution to simulate your RF environment, make sure the product’s internal modulation bandwidth is sufficient to cover your threat frequencies of interest.

The UXG agile signal generator’s ability to fast frequency hop with phase continuity and repeatability makes it an ideal source to efficiently simulate complex threat environments across the full 40 GHz range of the signal generator.

• Multiple pulse-Doppler radars at different frequencies while maintaining the original phase as the signal generator hops from one emitter frequency to another

• EW scenarios with thousands of radar threat-emitters and millions of pulses per second with unique antenna scans

• IQ custom complex modulation on pulse with the UXG Vector Adapter including linear and nonlinear frequency modulated chirps over a 40 GHz range (see Figure 4)

• High pulse density environments by scaling up in the number of UXGs increases pulse density and allows the ability to perform pulse-on-pulse simulations or do multi-port angle of arrival (AoA) simulations.

• AoA simulations with multiple UXGs and staggering identical pulses played out of different ports (different UXGs) in time, phase, amplitude, or all three1

Analysis and scoring of EW stimulus and electronic attack resources can be a challenge due to wide-bandwidth and complex pulse modulation types in highdensity environments. With the diverse portfolio of Keysight’s COTS analysis hardware including signal analyzers, oscilloscopes, and digitizers, you can capture and characterize the EW environment up to 110 GHz with wide modulation bandwidths.

Keysight N9067EM0E and 89601B pulse analysis software capabilities:

• Differentiate threats with pulse-scoring filters based on characteristics such as pulse width, PRI, and modulation type (including linear and non-linear modulation)

• Capture long scenarios with efficient memory usage

• Correlations and sidelobe measurements

• Dual domain analysis with narrow bandwidth for frequency domain analysis and wider bandwidth for time domain analysis

• Pulse Similarity Scores comparing sequential pulses assist with radar output waveform validation1

• Pulse Train Searches ensure that radar mode changes happen as expected1
