Description: Today's radar and electronic warfare (EW) equipment operate in increasingly cluttered RF and microwave spectral environments in the military theatre. Evaluating radar/EW hardware under a variety of emitter test signal scenarios helps determine the system performance in the presence of potential interference. Co‐existence between radar and wireless systems can be a significant issue. Capturing actual waveforms in the field and playing them back in the lab environment has utility in creating realistic spectral environments for hardware Device‐Under‐Test (DUT) evaluation. It may also be useful to modify a captured spectral environment with additional emitters to evaluate hardware in the lab environment over a number of different signal scenarios. This presentation will show how wide‐bandwidth, multi‐channel digitizers can be used to capture and analyze signals. Vector Signal Analysis (VSA) software will be used to both capture and analyze emitters. The captured signals will then be modified with design simulation software to add additional radar and wireless emitters to generate complex multi‐emitter test signals using a high precision Arbitrary Waveform Generator (AWG) and high performance signal generator. Coexistence and interference issues between radar and wireless emitters will be examined. « Less
