Investigation of Spectrum Signature Instrumentation

A relationship between pulse-power input to a receiver of finite bandwedth and a siustituted CW signal is derived. Experimntal data is obtained on narrow bandwidt. (optetrum analysers) and wide bancdwidth (RF-FI meters) receivers to verify the theoretical results. It is shovn that using the proposed method data collected on different bandwidth spectrum analysers can be correlated. Equations for power per unit bandwidth are also derived. The results indicate present correlation techniques are inadequate.
