Radar and EMSO Subsystem Test
Application Notes
The evolution from purely analog designs to hybrid analog/digital designs continues to drive advances in radar system capability and performance. Frequencies reach higher as signals become increasingly agile. Signal formats and modulation schemes—pulsed and otherwise—continue to evolve in complexity, demanding wider bandwidth. Advanced digital signal processing (DSP) techniques are used to disguise system operation and avoid jamming. Architectures such as active electronically steered arrays (AESA) rely on advanced materials such as gallium nitride (GaN) to implement phased-array antennas that enhance the performance of beamforming and beam steering.
This application note starts with the basics of radar and EW transmitters and receivers and the performance of different pulse-compression schemes. It covers how to choose the right instrument to generate signals to test components, receivers, and systems, as well as those needed for effective EW simulation.
