Abstract
A new technique for processing laser Doppler velocimeter signals by sampling spectrum analysis is presented. A swept‐filter spectrum analyzer and pulse‐shaping and sample‐and‐hold circuits are employed. Sampling turbulence frequencies up to 4 kHz. In contrast to most tracking techniques, high dropout of signal cases and high frequency signals normally associated with directionally sensitive velocimeter systems can be processed.Keywords
