Application Notes
The evolving requirements for advanced radar systems continue to pursue performance enhancements in key areas such as detection, ranging and tracking. As a result, frequencies keep reaching higher and signals are becoming increasingly agile. Signal formats and modulation schemes—pulsed and otherwise—continue to become more complex, and this demands wider bandwidth. These trends also have implications for those who create electronic-warfare systems.
Testing these systems—accurately and thoroughly—requires extremely realistic, phase-coherent signals. Those signals are part of very complex scenarios that have extremely long, perhaps infinite, play times. Arbitrary waveform generators (AWGs) are often the most effective solution.
To generate clean, wide-bandwidth radar pulses, an AWG must have 12- or 14-bit resolution coupled with sample rates that range from 8 to 12 GSa/s. Many current-generation AWGs can produce reasonably long signal scenarios through large memories and advanced sequencing capabilities. However, this may not be sufficient for the extremely long play times needed for radar testing. Instead, data compression combined with streaming from mass storage and high-speed decompression (in AWG hardware) is often the best way to produce virtually infinite play times.
