Application Brief
Modern Radar and electronic warfare (EW) systems operate in a variety of frequency bands with multi-emitter wideband signals and complex modulation schemes. They also use advanced Digital Signal Processing (DSP) techniques to attack or avoid being attacked by enemy’s EW systems. Because EW specifications are always adjusted based on the environment, today’s designers require a solution for designing, verifying and testing their EW systems in an effective way.
Problem
EW systems operate in complex environments with multi-emitter input signals from radar, military and commercial communication systems, as well as different interferences, noise and clutter. EW receivers must monitor the multi-emitter signals over a wide frequency range. When clutter or interference is significant, received signals become even more complex. This complexity poses a number of challenges when designing and testing Radar and EW systems, especially when coupled with new signal generation and processing requirements, and the need to analyze different test cases.
