Spectral and Noise Purity of Coherent Multiple-Frequency Chirp Exciter for L Band Radars
T. Cegielski, Zdzislaw Sawicki · 2006
This paper presents results of spectral analysis and design performance of the up-converter module of the coherent multiple-frequency chirp exciter for long distance L Band surveillance radars. Some measured results of spectral and noise purity of the exciter with coherent frequency synthesizer driven from high stability oscillator source are included. The experimental results are in good agreement with requested values.
